Abstract

Afin de mettre et de maintenir des êtres humains dans un état de détente tandis qu'un programme d'enseignement leur est transmis, des signaux multiplex droit et gauche (MR et ML) enregistrés sur un support de son sont obtenus et amplifiés dans un dispositif de reproduction (60). Des signaux audio et des signaux de commande à fréquence modulée sont obtenus à partir de ces signaux multiplex amplifiés au moyen d'étages filtres (66, 68, 70, 72) correspondants. Les signaux de commande à fréquence modulée sont démodulés, amplifiés puis utilisés pour commander une source lumineuse (20; 22), alors que les signaux audio sont rendus acoustiquement perceptibles. Les signaux lumineux et une partie des signaux audio produisent un état de détente chez les êtres humains, tandis que l'autre partie des signaux audio sert à transmettre l'information. Etant donné que les signaux de commande sont enregistrés sur le porteur de son pendant l'enregistrement du programme d'enseignement, on peut obtenir une coordination, c'est-à-dire la mise en accord et l'adaptation des signaux de commandes en fonction du contenu d'information de la matière à enseigner dispensé à un moment précis.In order to put and maintain human beings in a state of relaxation while a teaching program is transmitted to them, right and left multiplex signals (MR and ML) recorded on a sound medium are obtained and amplified in a device. reproduction (60). Audio signals and frequency modulated control signals are obtained from these amplified multiplex signals by means of corresponding filter stages (66, 68, 70, 72). The frequency modulated control signals are demodulated, amplified and then used to control a light source (20; 22), while the audio signals are made acoustically perceptible. Light signals and part of the audio signals produce a state of relaxation in humans, while the other part of the audio signals is used to transmit information. Since the control signals are recorded on the sound carrier during the recording of the teaching program, coordination can be achieved, i.e. the tuning and adaptation of the control signals in based on the information content of the subject to be taught at a specific time.

Description

Verfahren zur Wissensvermittlung Knowledge transfer procedures
Die Erfindung betrifft ein Verfahren zur Wissensvermitt¬ lung,bei dem in einer Vorbereitungsstufe Sprachinforma¬ tionen auf einem Tonträger aufgezeichnet und von diesem in einer Anwendungsstufe akustisch für den Anwender wahr¬ nehmbar gemacht werden und bei dem mittels Impulsgenerato¬ ren elektrische Steuersignale erzeugt werden, die zur Beein¬ flussung des elektrischen Gehirnwellenbildes des Anwen¬ ders während der Anwendungsstufe in niederfrequente, vom Anwender wahrzunehmende optische und akustische Signale umgewandelt werden.The invention relates to a method for imparting knowledge in which, in a preparation stage, voice information is recorded on a sound carrier and made audible to the user in an application stage, and in which electrical control signals are generated by means of pulse generators to influence the electrical brain wave image of the user during the application stage are converted into low-frequency optical and acoustic signals to be perceived by the user.
Ein solches Verfahren ist unter dem Begriff "Superlearning" bekannt (MEGABRAIN : Geist und Maschine v- Michael Hutchinson, SPHINX Medien Verlag, Basel 1989, Seite 92 ff) . Diese Tech¬ nik beruht darauf, den Anwender in einen Entspannungszu¬ stand zu versetzen. Dazu ist es erforderlich, das Schwingungsmuster der Gehirnwellen zu verändern und zwar vom Beta-Zustand (Beta-Wellen haben eine Frequenz im Ber- reich von etwa 14 - 30 Hz und kleine Schwingungsampituden) in den Alpha-Zustand (8-14 Hz und größere Amplituden) oder sogar in den Theta-Zustand (3-7 Hz und hohe Amplituden) . Dazu gibt man ein äußeres Impulsfrequenzfeld vor. Wird die¬ ses vom Gehirn wahrgenommen, schwingt sich das Gehirn¬ wellenfeld darauf ein und versucht sozusagen in Resonanz zu kommen. Dazu kann ein Impulsgenerator entweder mittels an den Ohrläppchen des Anwenders angelegter Elektroden di¬ rekt Stromimpulse dem Gehirn zuführen oder die Impulse werden dem Gehirn indirekt optisch und/oder akustisch zu¬ geführt. Für den letzteren Fall werden eine Brille und ein Kopfhörer verwendet. Statt der Brillengläser sind Glühbirnen oder LED's vorgesehen, die vom Impulsgenerator angesteuert werden und deren Aufleuchten bei geschlossenen Augen wahr¬ genommen wird. Versuche haben gezeigt, daß nach etwa 15-minütiger Behandlung des Menschen mit optischer und ggf. akustisch verstärkter Impulsbeaufschlagung von etwa 8 Hz der tiefentspannte Alpha-Zustand des Gehirnwellen¬ bildes erreicht wird. Der Anwender hat dann einen hohen Aufmerksamkeitsgrad und die ihm in diesem Zustand vermit¬ telten Informationen vermag er sich anzueignen, zu verar¬ beiten und zu speichern.Such a method is known under the term "superlearning" (MEGABRAIN: Geist und Maschine v- Michael Hutchinson, SPHINX Medien Verlag, Basel 1989, page 92 ff). This technique is based on putting the user in a state of relaxation. To do this, it is necessary to change the vibration pattern of the brain waves from the beta state (beta waves have a frequency in the range of around 14 - 30 Hz and small vibrational amplitudes) to the alpha state (8-14 Hz and larger ones) Amplitudes) or even in the theta state (3-7 Hz and high amplitudes). An external pulse frequency field is specified for this. If this is perceived by the brain, the brain wave field swings into it and tries to resonate, so to speak get. For this purpose, a pulse generator can either supply current pulses directly to the brain by means of electrodes placed on the user's earlobes, or the pulses are indirectly fed to the brain optically and / or acoustically. In the latter case, glasses and headphones are used. Instead of the spectacle lenses, light bulbs or LEDs are provided which are controlled by the pulse generator and whose lighting is perceived when the eyes are closed. Experiments have shown that after about 15 minutes of treatment of humans with optical and possibly acoustically amplified impulse application of about 8 Hz, the deeply relaxed alpha state of the brain wave image is achieved. The user then has a high degree of attention and can acquire, process and save the information conveyed to him in this state.
Bei dem bekannten Verfahren wird ein Impulsgenerator ver¬ wendet, der aus einem Steuergerät mit einem festprogrammier¬ ten oder frei programmierbaren Mikrokontroller besteht. Das Steuergerät umfaßt auch einen Tongenerator. In einem externen Widergabegerät wird der in der Vorbereitungsstufe bespielte Tonträger abgespielt und die Tonsignale werden denjenigen des Tongenerators überlagert, sodaß dem Anwen¬ der das auf dem Tonträger gespeicherte Lernprogramm zu¬ geführt wird, während er gleichzeitig die niederfrequenten optischen und akustischen Signale wahrnimmt.In the known method, a pulse generator is used, which consists of a control unit with a permanently programmed or freely programmable microcontroller. The control unit also includes a tone generator. The sound carrier recorded in the preparation stage is played in an external playback device and the sound signals are superimposed on those of the sound generator, so that the learning program stored on the sound carrier is supplied to the user while at the same time the low-frequency perceives optical and acoustic signals.
Zwar läßt sich bei einigen Impulsgeneratoren die Frequenz in einem gewissen Bereich einstellen, sodaß der Anwender je nach seinem subjektiven Empfinden die Impulsfrequenz allmählich weiter senken kann, jedoch bleiben die Steuer¬ impulse von dem Inhalt des Tonträgers im Abspielgerät un¬ abhängig.Although with some pulse generators the frequency can be set within a certain range, so that the user can gradually lower the pulse frequency depending on his subjective feeling, the control pulses remain independent of the content of the sound carrier in the player.
Aufgabe der Erfindung ist es, das bekannte Verfahren dahin¬ gehend zu verbessern, daß eine Koordination der Impulsmuster für die Steuersignale und des Programms auf dem Tonträger ermöglicht wird. Mit der Erfindung soll es möglich sein, die Steuersignale zur Beeinflussung des Gehirnwellenzustan- des hinsichtlich ihrer charakterischen Eigenschaf en dem momentanen Informationsgehalt des Tonträgers optimal anzu¬ passen.The object of the invention is to improve the known method in such a way that the pulse patterns for the control signals and the program on the sound carrier can be coordinated. The aim of the invention is to be able to optimally adapt the control signals for influencing the state of the brain wave with regard to their characteristic properties to the current information content of the sound carrier.
Zur Lösung dieser Aufgabe ist erfindungsgemäß vorgesehen, daß die elektrischen Steuersignale während der Vorberei¬ tungsstufe in Koordination mit der Informationsaufzeich¬ nung auf demselben Tonträger aufgezeichnet werden und von diesem während der Anwendungsstufe gleichzeitig mit den Informationen abgenommen, separat aufbereitet und dem Anwender zugänglich gemacht werden. Erfindungsgemäß erfolgt also die Erzeugung der Licht- und Tonsignale an zentraler Stelle, z.B. beim Hersteller von Superlearning-Medien, wobei von vornherein auf die Koordi¬ nation der Impulsmuster besonderer Wert gelegt wird. Die zeitliche Abfolge der Licht-und Tonimpulse wird also er¬ findungsgemäß nicht mehr in Form eines Programmes für ei¬ nen Mikrokontroller in der Anwendungsstufe gesteuert son¬ dern ist direkt auf dem Tonträger gespeichert. Dank der Erfindung werden die Wiedergabegeräte wesentlich einfacher, da in der Anwenderstufe kein Steuergerät mit Tongenerator und Mikrokontroller mehr erforderlich ist. Beim Hersteller des Lernprogra mes können aufwendigere Mittel eingesetzt werden, um das Steuersignal-Programm dem Lernprogramm opti¬ mal anzupassen. Es können Tests durchgeführt werden, um die Koordination zu vervollkommnen. Dadurch wird letztendlich die Effektivität des Kombinationsprogramms gesteigert.To achieve this object it is provided according to the invention that the electrical control signals are recorded in coordination with the information recording on the same sound carrier during the preparation stage and are simultaneously accepted with the information during the application stage, processed separately and made accessible to the user. According to the invention, the light and sound signals are thus generated at a central point, for example at the manufacturer of superlearning media, with particular emphasis being placed on the coordination of the pulse patterns from the outset. According to the invention, the chronological sequence of the light and sound pulses is therefore no longer controlled in the form of a program for a microcontroller in the application stage, but is stored directly on the sound carrier. Thanks to the invention, the playback devices become much simpler, since in the user level no control device with a tone generator and microcontroller is required. The manufacturer of the learning program can use more complex means to optimally adapt the control signal program to the learning program. Tests can be performed to improve coordination. This ultimately increases the effectiveness of the combination program.
Da die Erstellung eines derartigen Kombinationsprogrammes sehr aufwendig ist, muß für einen Kopierschutz gesorgt werden. Dies wird bei dem erfindungsgemäßen Verfahren dadurch er¬ reicht, daß die in der Vorbereitungsstufe digital aufzuzeich¬ nenden Sprachinformationen und/oder die Steuersignale durch bewußten Einbau von Übertragungsfehlern verschlüsselt aufge¬ zeichnet werden und daß die Übertragungsfehler durch ein Feh¬ lererkennungsprogramm in der Anwendungsstufe eliminiert werden. Dabei werden vorzugsweise keine Steuersignale mehr aufgezeich¬ net, da die Steuerinformation in den Übertragungsfehlern co¬ diert enthalten ist. Die Erfindung betrifft weiterhin ein Wiedergabegerät zum Abspielen von Tonträgern, insbesondere zur Verwendung bei dem erfindungsgemäßen Verfahren. Das Wiedergabegerät ist dadurch gekennzeichnet, daß die Ausgangsleitung des den Tonträger abtastenden Tastkopfes ggf. hinter einem Ver¬ stärker in eine Tonleitung und eine Lichtsteuerleitung verzweigt und daß in ersterer ein, in einem schmalen Frequenzbandsperrendes Bandsperrenfilter sowie ein Ver¬ stärker und in letzterer ein nur in dem schmalen Fre¬Since the creation of such a combination program is very complex, copy protection must be provided. This is achieved in the method according to the invention in that the voice information to be digitally recorded in the preparation stage and / or the control signals are recorded in encrypted form by deliberately incorporating transmission errors and in that the transmission errors are eliminated by an error detection program in the application stage . In this case, preferably no more control signals are recorded, since the control information is contained in coded form in the transmission errors. The invention further relates to a playback device for playing sound carriers, in particular for use in the method according to the invention. The playback device is characterized in that the output line of the probe scanning the sound carrier branches, if necessary, behind an amplifier into a sound line and a light control line, and that in the former there is a band-stop filter and a amplifier in a narrow frequency band, and in the latter an only in the narrow Fre¬
quenzband durchlässiges Bandpaßfilter, ein Demodulator und ein Verstärker angeordnet sind und daß an die Tonleitung ein Lautsprecher oder Kopfhörer und an die Lichtsteuerlei¬ tung eine.Lichtquelle angeschlossen oder anschließbar sind.Quenzband permeable bandpass filter, a demodulator and an amplifier are arranged and that a loudspeaker or headphones are connected to the sound line and a light source is or can be connected to the light control line.
Die Erfindung betrifft weiterhin einen Tonträger, der ins¬ besondere bei dem erfindungsgemäßen Verfahren und/oder in dem vorgenannten erfindungsgemäß ausgebildeten Wiedergabe¬ gerät verwendet wird. Dieser Tonträger ist dadurch gekenn - zeichnet, daß auf mindestens einer Spur Multiplexsignale aufgezeichnet sind, die sich aus unkodierten Tonsignalen und trägerfrequenzmodulierten, niederfrequenten impulsket¬ ten im Bereich von 1-30 Hz zusammensetzen. Da das Wieder¬ gabegerät vorzugsweise mit Stereoton arbeitet, reichen zwei Spuren des Tonträgers aus, um sowohl die Sprach- und Musik¬ information als auch die Steuersignale aufzeichnen zu kön¬ nen. Die Trägerfrequenz für die Steuersignale liegt vor¬ zugsweise oberhalb 10 kHz und beträgt vorzugsweise 11,5 kHz, Die Erfindung bezieht sich weiterhin auf eine Aufnahmeein¬ richtung zur Sprachaufzeichnung, die insbesondere beim er¬ findungsgemäßen Verfahren verwendet wird. Diese Aufnahme- einrichtung ist dadurch gekennzeichnet, daß eine Mischstufe vorgesehen ist, der Tonsignale aus einer ersten Tonquelle und solche aus einer zweiten Tonquelle zuführbar sind, daß aus einem Steuergerät niederfrequente Impulsketten im Be¬ reich von 1-30 Hz in einem Modulator auf eine Trä¬ gerfrequenz oberhalb 10 kHz aufmoduliert werden und die modulierten Steuersignale ggf. zur Bandbegrenzung eine Filterstufe durchlaufen, daß an die Tonquellenmischstufe eine Filterstufe angeschlossen ist, die im Bereich der Trä¬ gerfrequenz sperrt, daß die modulierten ggf. gefilterten Steuersignale und die addierten gefilterten Tonsignale je¬ weils verstärkt werden, und daß aus ihrer Addition ein Mul- tiplexsignal gewonnen wird, das auf einem Tonträger auf¬ gezeichnet wird.The invention further relates to a sound carrier which is used in particular in the method according to the invention and / or in the aforementioned playback device designed according to the invention. This sound carrier is characterized in that multiplex signals are recorded on at least one track, which are composed of uncoded sound signals and carrier frequency modulated, low frequency impulsket ¬ th in the range of 1-30 Hz. Since the playback device preferably works with stereo sound, two tracks of the sound carrier are sufficient to be able to record both the speech and music information and the control signals.

Das bekannte Verfahren wird anhand von FIG. 1 erläutert. Die Wiedergabeeinrichtung 10 weist zwei Komponenten,nämlich eine externe Tonquelle 12, z.B. ein Tonbandgerät oder einen Kompaktdisc-Player sowie ein Steuergerät 14 mit Mikrokontrol¬ ler und Impulsgenerator auf. Das Steuergerät 14 und die Ton¬ quelle 12 arbeiten im Stereobetrieb. Das Steuergerät hat einen rechten Steuerausgang S_ und einen linken Steuerausgang S- sowie einen rechten Tonausgang Txv und einen linken TonausgangThe known method is shown in FIG. 1 explained. The playback device 10 has two components, namely an external sound source 12, e.g. a tape recorder or a compact disc player and a control unit 14 with a microcontroller and pulse generator. The control device 14 and the sound source 12 operate in stereo mode. The control unit has a right control output S_ and a left control output S- as well as a right sound output Txv and a left sound output
T . Die externe Tonquelle 12 hat einen rechten Ausgang E_ und einen linken Ausgang E . Die rechten und die linken Tonaus¬ gänge des Steuergerätes 14 und der externen Tonquelle 12 wer¬ den jeweils addiert. Die addierten linken und die addisrten rechten Signale werden getrennt verstärkt und jeweils einem Kopfhörer 16 bzw. 18 zugeführt. Die Steuerausgänge S und SL werden separat verstärkt und steuern jeweils eine Lichtquelle 20 bzw. 22 an. Diese Lichtquellen 20,22 bestehen aus LED-Grup- pen, die in einer Brille vor den Augen des Anwenders an¬T. The external sound source 12 has a right output E_ and a left output E. The right and left sound outputs of the control device 14 and the external sound source 12 are added together. The added left and added right signals are amplified separately and fed to headphones 16 and 18, respectively. The control outputs S and S L are amplified separately and each control a light source 20 or 22. These light sources 20, 22 consist of LED groups pen that in glasses in front of the eyes of the user
geordnet sind.are ordered.

Tτi Impulsketten aus, die zwar programmierbar sind, jedoch keine Beziehung zu dem jeweiligen Tonträger in der externen Tonquelle 12 haben.The control unit 14 sends via the outputs S_. or S τ and T_ R. or T τ i pulse chains, which are programmable, but have no relation to the respective sound carrier in the external sound source 12.
In FIG. 3 ist nun eine Aufnahmeeinrichtung anhand eines Blockschaltbildes gezeigt, mit der es möglich ist, die Steuersignale für die Licht- und Tonsteuerung auf der Her¬ stellerseite des Informationsprogrammes zu erzeugen und auf ein und denselben Tonträger zu übertragen. Die Auf- zeichnungseinrichtung 30 besteht aus einer externen Ton¬ quelle 32 und einem Steuergerät 34 . Die externe Tonquelle kann aus einem Tonband oder dergl. bestehen, von dem das vorher aufgenommene Lernprogramm abgespielt wird. Die Ton¬ quelle kann aber auch ein Mikrofon sein, um während der Aufnahme des Lernprogrammes Licht- und Tonsteuersignale hinzuzufügen. Das Steuergerät 34 ist mit Reglern ausgestat¬ tet, um die charakteristischen Werte der Steuersignale, wie Frequenzen, Amplituden und Intensitäten beeinflußen und mit den jeweiligen Tonsignalen der externen Tonquelle 32 koor¬ dinieren zu können.In FIG. 3 shows a recording device based on a block diagram, with which it is possible to generate the control signals for the light and sound control on the manufacturer side of the information program and to transmit them to one and the same sound carrier. The recording device 30 consists of an external sound source 32 and a control device 34. The external sound source may consist of a tape or the like from which the previously recorded learning program is played. However, the sound source can also be a microphone in order to add light and sound control signals during the recording of the learning program. The control unit 34 is equipped with regulators in order to influence the characteristic values of the control signals, such as frequencies, amplitudes and intensities, and to be able to coordinate them with the respective sound signals of the external sound source 32.
Die beiden Tonsignale T_ und T- aus dem Steuergerät 34 und die Tonsignale E_K, und Eτ _ aus der externen Tonquelle 32 werden jeweils zu den Summensignalen + E_K. und TJτ_ι + EJτ-j addiert und einem Tiefpaß-oder Bandsperrenfilter 36 bzw. 38 zugeführt. Ein Trägerfrequenzgenerator 40 erzeugt eine Trägerfrequenz von 11,5 kHz. In Modulatoren 42,44 z.B. zur Amplituden¬ modulation werden die Steuersignale S-, und Sτ des Steuergerätes 34 auf diese Trägerfrequenz aufmoduliert. Um die Störungen durch dieses modulierte Signal im Bereich der Tonübertragung zu verringern, wird dieses Signal je nach verwendetem Modu¬ lationsverfahren bandbegrenzt und zwar durch einen Hochpa߬ oder Bandpaßfilter 46 bzw. 48. Um eine Störung des träger- frequenten Signals zu verhindern sind die Tiefpaßfilter 36, 38 in den Tonleitungen vorgesehen. Diese Filter 36, 38 sor¬ gen dafür, daß das Frequenzgebiet um die Trägerfrequenz herum ausgespart bleibt. Die gefilterten Tonsignale und die gefilterten modulierten Steuersignale werden verstärkt und addiert. Die so gewonnenen Multiplexsignale M_ und M_ werden einem Aufnahmegerät 50, z.B. einem Tonbandgerät zu¬ geführt, in dem die Multiplexsignale auf dem Tonträger auf¬ gezeichnet werden.The two sound signals T_ and T- from the control unit 34 and the sound signals E_K, and E τ _ from the external sound source 32 become the sum signals, respectively + E_K. and TJ τ _ι + EJ τ -j added and fed to a low-pass filter or band-stop filter 36 and 38, respectively. A carrier frequency generator 40 generates a carrier frequency of 11.5 kHz. In modulators 42,44 for example, modulation to Amplituden¬ the control signals S-, and S τ of the control unit 34 is modulated onto this carrier frequency. In order to reduce the interference caused by this modulated signal in the area of the sound transmission, this signal is band-limited, depending on the modulation method used, namely by a high-pass or band-pass filter 46 or 48. The low-pass filters are used to prevent interference with the carrier-frequency signal 36, 38 provided in the sound lines. These filters 36, 38 ensure that the frequency range around the carrier frequency is left out. The filtered audio signals and the filtered modulated control signals are amplified and added. The multiplex signals M_ and M_ obtained in this way are fed to a recording device 50, for example a tape recorder, in which the multiplex signals are recorded on the sound carrier.
FIG. 2 erläutert das Frequenzspektrum der Multiplexsignale. Die Spektren des Basisbandsignals und des trägerfrequenten Signals sollen sich zur Vermeidung von gegenseitigen Stö¬ rungen möglichst wenig überlappen. Da die Multiplexsignale auf einem Speichermedium z.B. Tonband gespeichert werden, muß die Trägerfrequenz des kodierten Steuersignals im Über- tragungsbereich dieses Speichermediums, im allgemeinen also im Tonfrequenzbereich liegen und ist gemäß FIG. 2 am Ende des Übertragungsbereiches angeordnet. Die schraffierte Fläche 52 stellt das Tonsignal T + E im Basisband dar und die Fläche 54 bezeichnet das Steuersignal S in Trägerfre¬ quenzlage. Der Frequenzbereich 56 ist der Übertragungsbe¬ reich des Speichermediums.FIG. 2 explains the frequency spectrum of the multiplex signals. The spectra of the baseband signal and the carrier-frequency signal should overlap as little as possible to avoid mutual interference. Since the multiplex signals are stored on a storage medium, for example tape, the carrier frequency of the coded control signal must be Carrying area of this storage medium, generally in the audio frequency range and is shown in FIG. 2 arranged at the end of the transmission range. The hatched area 52 represents the sound signal T + E in the baseband and the area 54 denotes the control signal S in the carrier frequency position. The frequency range 56 is the transmission range of the storage medium.
FIG. 4 zeigt ein Blockschaltbild einer Wiedergabeeinrich¬ tung. Diese besteht aus einem Abspielgerät 60 mit zwei Ton- kδpfen zur Rückgewinnung der Multiplexsignale M^ und M von zwei Spuren des Tonträgers. Die beiden Multiplexsignale werden verstärkt und jeweils in eine Tonleitung 62 und eine Lichtleitung 64 verzweigt, um den Basisbandanteil über Tief- paß-oder Bandsperrenfilter 66, 68 vom trägerfrequenten Teil über Hochpaß-oder Bandpaßfilter 70, 72 in der jeweiligen Lichtsteuerleitung 64 zu trennen. Die so zurückgewonnenen Tonsignale T + E und T + E werden verstärkt und der Aus¬ gabeeinheit z.B. den Kopfhörern 16, 18 zugeführt. In geeig¬ neten Demulatoren 74,76 werden aus den trägerfrequenten Sig¬ nalen die ursprünglichen Steuersignale S_ K und SτL wieder her- gestellt, die verstärkt zur Ausgabeeinheit, nämlich den Lichtquellen geführt werden. FIG. 4 shows a block diagram of a playback device. This consists of a playback device 60 with two sound heads for recovering the multiplex signals M ^ and M from two tracks of the sound carrier. The two multiplex signals are amplified and each branched into a sound line 62 and a light line 64 in order to separate the baseband portion via low-pass or band-stop filters 66, 68 from the carrier-frequency part via high-pass or band-pass filters 70, 72 in the respective light control line 64. The sound signals T + E and T + E thus recovered are amplified and fed to the output unit, for example the headphones 16, 18. In geeig¬ Neten Demulatoren 74.76 are obtained from the carrier-dimensional Sig¬ the original control signals S_ K and S τ L asked manufacturers again, which amplifies the light sources are guided to the output unit, viz.
