Das Addierglied 45 ist eingangsseitig mit einem Ausgang eines Multiplikationsglieds 49 verbunden. Das Multiplikationsglied 49 ist eingangsseitig mit einem Frequenzeingang 47 des Tonsignalgenerators 43 verbunden. Das Multiplikationsglied 49 ist auch eingangsseitig mit einem Ausgang eines Vibratoglieds 52 zum Erzeugen einer Frequenzmodulation verbunden. Das Vibratoglied 52 ist eingangsseitig mit einem Triggereingang 53 des Tonsignalgenerators 43 verbunden. Das Multiplikationsglied 49 ist ausgebildet, eingangsseitig empfangene Signale zu multiplizieren und ein Ausgangssignal zu erzeugen, welches dem Multiplikationsergebnis entspricht. Fig. 2 shows an embodiment of a tone signal generator 43, which for example at least partially the in Fig. 1 represented tone signal generator 11, 13 or 15 can form. The tone signal generator 43 has a feedback input 44, which is connected to a first input of an adder 45 of the tone signal generator 43. The tone signal generator 43 also has an adder 46 which is connected on the input side to an output of the adder 45. The adder 45 is connected on the input side to an output of a multiplication element 49.

Die Addierglieder 45 und 46 sind jeweils ausgebildet, eingangsseitig empfangene Signale miteinander zu addieren und ein Ausgangssignal zu erzeugen, welches einer Summe der eingangsseitig empfangenen Signale entspricht. Das Addierglied 46 ist ausgangsseitig mit einem Moduloglied 54 des Tonsignalgenerators 43 verbunden. Das Moduloglied 54 ist eingangsseitig auch mit einem Wellenlängenspeicher 45 verbunden. Das Moduloglied 54 ist ausgebildet, das von dem Addierglied 46 empfangene Ausgangssignal durch den von dem Wellenlängenspeicher 55 empfangenen Zahlenwert zu dividieren und ein Ausgangssignal zu erzeugen, welches den Divisionsrest repräsentiert und dieses ausgangsseitig auszugeben. Das Moduloglied 54 ist ausgangsseitig mit einem Eingang eines Verzögerungsglieds 56 verbunden. Das Verzögerungsglied 56 ist ausgangsseitig mit einem Eingang des Addierglieds 46 verbunden. Somit wird ein durch das Moduloglied 54 erzeugtes Ausgangssignal zwischengespeichert und für eine folgende Rechenoperation durch Summenbildung berücksichtigt. Das Moduloglied 54 ist ausgangsseitig auch mit einem Rundungsglied 57 verbunden. Das Rundungsglied ist in dieser Ausführungsform ausgebildet, ein eingangsseitig empfangenes Eingangssignal, welches einen Zahlenwert repräsentiert, auf einem Zahlenwert mit einer vorbestimmten Nachkommastellenzahl zu runden.

Das Rundungsglied 57 ist ausgangsseitig mit einem Wellenformspeicher 58 des Tonsignalgenerators 43 verbunden.The adders 45 and 46 are each configured to add together signals received on the input side and to generate an output signal which is a sum of the input side corresponds to received signals. The adder 46 is connected on the output side to a modulo song 54 of the tone signal generator 43. The modulo song 54 is also connected to a wavelength memory 45 on the input side. The modulo song 54 is configured to divide the output signal received from the adder 46 by the numerical value received by the wavelength memory 55 and to generate an output signal representing the remainder of the division and to output this output side. The modulo member 54 is connected on the output side to an input of a delay element 56. The delay element 56 is connected on the output side to an input of the adder 46. Thus, an output signal produced by the modulo member 54 is latched and taken into account for a following arithmetic operation by summation.

In this embodiment, the rounding element is designed to round an input signal received on the input side, which represents a numerical value, to a numerical value with a predetermined number of decimal places. In this embodiment, the rounding member is configured to generate an output signal representing an integer rounding result. The rounding member 57 is connected on the output side to a waveform memory 58 of the tone signal generator 43.

Der Wellenformspeicher 58 kann als Look-Up-Tabelle ausgebildet sein und hält zeitlich aufeinander folgende Abtastwerte einer abgetasteten Wellenperiode vorrätig, welche jeweils einem Index zugeordnet sind. Die Abtastwerte repräsentieren jeweils einen Amplitudenwert zu einem Abtastzeitpunkt. Der Abtastzeitpunkt wird im Folgenden auch Index genannt. Der Wellenspeicher 58 ist ausgebildet, einen Index auszuwählen, welcher einem eingangsseitig empfangenen Signal entspricht und ein Ausgangssignal zu erzeugen, welches eines dem ausgewählten Index zugeordneten Amplitudenwert repräsentiert.The waveform memory 58 may be formed as a look-up table and holds temporally successive samples of a sampled wave period, each associated with an index. The samples each represent an amplitude value at a sampling instant. The sampling time is also called index below. The shaft memory 58 is configured to select an index which corresponds to a signal received on the input side and to generate an output signal representing an amplitude value associated with the selected index.

Der Wellenlängenspeicher 55 hält eine Zahl der in dem Wellenspeicher 58 vorrätig gehaltenen Abtastwerte vorrätig. Das Moduloglied 54 bewirkt in Verbindung mit dem Wellenlängenspeicher 55, dass von dem Addierglied 45 empfangene Signale auf die in dem Wellenspeicher 58 vorrätigen Indizes abgebildet werden. Der Wellenspeicher 58 ist ausgangsseitig mit einem ersten Eingang eines Multiplikationsglieds 59 verbunden. Ein zweiter Eingang des Multiplikationsglieds 59 ist mit einem Ausgang eines einhüllenden Glieds 60 verbunden. Das Multiplikationsglied 59 ist ausgangsseitig mit einem ersten Eingang eines Multiplikationsglieds 61 verbunden. Ein zweiter Eingang eines Multiplikationsglieds 61 ist mit einem Ausgang eines als Amplitudenmodulationsglied ausgebildeten Tremologlieds verbunden. Das Multiplikationsglied 61 ist ausgangsseitig mit einem Ausgang 64 des Signalgenerators 43 verbunden. Das Einhüllendenglied 60 weist einen Triggereingang auf, welcher mit dem Triggereingang 53 des Tonsignalgenerators 43 verbunden ist. Das Tremologlied 62 weist einen Triggereingang auf, welcher mit dem Triggereingang 53 des Tonsignalgenerators 43 verbunden ist. Das Einhüllendenglied 60 weist einen Ton-Stoppeingang auf, welcher mit einem Ton-Stoppeingang 63 des Tonsignalgenerators 43 verbunden ist.The wavelength memory 55 holds a number of samples held in the shaft memory 58 in stock. The modulo member 54, in conjunction with the wavelength memory 55, causes signals received from the adder 45 to be mapped to the indexes stored in the shaft memory 58. The shaft memory 58 is connected on the output side to a first input of a multiplication element 59. A second input of the multiplier 59 is connected to an output of an envelope member 60. The multiplication element 59 is connected on the output side to a first input of a multiplication element 61. A second input of a multiplication element 61 is connected to an output of a tremolo song designed as an amplitude modulation element. The multiplication element 61 is connected on the output side to an output 64 of the signal generator 43. The envelope element 60 has a trigger input, which is connected to the trigger input 53 of the tone signal generator 43. The tremolo song 62 has a trigger input, which is connected to the trigger input 53 of the tone signal generator 43. The envelope member 60 has a tone stop input which is connected to a tone stop input 63 of the tone signal generator 43.

Die Funktionsweise des Tonsignalgenerators 43 wird nun im Folgenden beschrieben:The operation of the tone signal generator 43 will now be described below:

Wenn ein Triggersignal an dem Triggereingang 53 anliegt, kann das Vibratoglied 52 in Abhängigkeit von dem eingangsseitig empfangenen Triggersignal eine Modulationsfrequenz erzeugen und dies ausgangsseitig ausgeben. Eine an dem Frequenzeingang 47 anliegende Frequenz wird durch das Multiplikationsglied 49 mit der durch das Vibratoglied 52 erzeugten Modulationsfrequenz multipliziert und an das Addierglied 45 ausgegeben. Im Falle keiner Rückkopplung wird das von dem Multiplikationsglied 49 erzeugte Ausgangsignal von dem Addierglied 45 ausgangsseitig an das Addierglied 46 ausgegeben. Die zu erzeugende Frequenz wird nun im folgenden Signalverlauf durch das Moduloglied 54, den Wellenlängenspeicher 55 und das Verzögerungsglied 56, und weiter in Verbindung mit dem Rundungsglied 57 auf die in dem Wellenspeicher 58 vorrätig gehaltenen Indizes abgebildet. Das Einhüllendenglied 60 erzeugt in Abhängigkeit von dem eingangsseitig empfangenen Triggersignal ein Ausgangssignal, welches zusammen mit dem von dem Wellenspeicher 58 ausgegebenen Signal durch das Multiplikationsglied 59 multipliziert wird. Das Tremologlied 62 erzeugt in Abhängigkeit von dem am Triggereingang 53 empfangenen Triggersignal ein Amplitudenmodulationssignal, welches zusammen mit dem von dem Multiplikationsglied 59 erzeugten Ausgangssignal von dem Multiplikationsglied 61 eingangsseitig empfangen und multipliziert wird. Das Multiplikationsglied 61 erzeugt ausgangsseitig ein Ausgangssignal, welches dem Multiplikationsergebnis entspricht und stellt dieses ausgangsseitig am Ausgang 64 des Tonsignalgenerators 43 zur Verfügung. Im Falle eines Ton-Stoppsignals, welches am Ton-Stoppeingang 63 anliegt, erzeugt das Einhüllendenglied ein Ausgangssignal, welches den Wert 0 repräsentiert, so dass das durch das Multiplikationsglied 59 erzeugte Ausgangssignal ebenfalls einen Wert 0 repräsentiert.When a trigger signal is applied to the trigger input 53, the vibrato song 52 can generate a modulation frequency in response to the trigger signal received on the input side and output this on the output side. A frequency applied to the frequency input 47 is determined by the multiplier 49 multiplied by the modulation frequency generated by the vibrato song 52 and output to the adder 45. In the case of no feedback, the output signal generated by the multiplication element 49 is output by the adder 45 on the output side to the adder 46. The frequency to be generated is now mapped in the following signal waveform by the modulo member 54, the wavelength memory 55 and the delay element 56, and further in conjunction with the rounding member 57 on the indices held in the shaft memory 58. The envelope member 60 generates an output signal in response to the trigger signal received on the input side, which output signal is multiplied by the multiplier 59 together with the signal output from the wave memory 58. The tremolo member 62 generates an amplitude modulation signal in response to the trigger signal received at the trigger input 53, which is received and multiplied on the input side of the multiplier 61 together with the output signal generated by the multiplier 59. On the output side, the multiplication element 61 generates an output signal which corresponds to the multiplication result and makes this output available at the output 64 of the tone signal generator 43. In the case of a tone stop signal, which is applied to the tone stop input 63, the envelope member generates an output signal which represents the value 0, so that the output signal generated by the multiplier 59 also represents a value 0.

Der in Figur 2 dargestellte Tonsignalgenerator kann mit wenigstens einem weiteren Tonsignalgenerator parallel oder seriell verbunden sein.
Bei der parallelen Verbindung sind die Frequenzeingänge der Tonsignalgeneratoren jeweils mit einem gemeinsamen Frequenzeingang verbunden. Die Ausgänge der zueinander parallel geschalteten Tonsignalgeneratoren sind miteinander verbunden. Beispielsweise ist im Falle zwei zueinander parallel geschalteter Tonsignalgeneratoren ein erster Tonsignalgenerator über ein Verstärkungsglied vom Ausgang zum Rückkopplungseingang rückgekoppelt. Ein Rückkopplungseingang eines zweiten Tonsignalgenerators ist mit einem Wert 0 belegt, was keiner Frequenz oder einer Frequenz von 0 Hertz entspricht.The in FIG. 2 shown tone signal generator may be connected in parallel or in series with at least one further tone signal generator.
In the case of the parallel connection, the frequency inputs of the tone signal generators each have a common frequency input connected. The outputs of the mutually parallel tone signal generators are interconnected. For example, in the case of two mutually parallel tone signal generators, a first tone signal generator is fed back via a gain element from the output to the feedback input. A feedback input of a second audio signal generator is assigned a value 0, which corresponds to no frequency or a frequency of 0 hertz.

Bei der seriellen Verbindung ist ein Ausgang eines ersten Tongenerators mit einem Rückkopplungseingang des zweiten Tonsignalgenerators verbunden. Der erste Tonsignalgenerator ist über ein Verstärkungsglied von seinem Ausgang zu seinem Rückkopplungseingang rückgekoppelt.
Die Frequenzeingänge der Tonsignalgeneratoren sind miteinander verbunden und bilden einen gemeinsamen Frequenzeingang. Mittels der parallelen oder der seriellen Verbindung kann jeweils ein obertonreiches Audiosignal erzeugt werden.In the serial connection, an output of a first tone generator is connected to a feedback input of the second tone signal generator. The first tone signal generator is fed back via a gain element from its output to its feedback input.
The frequency inputs of the tone signal generators are connected to each other and form a common frequency input. By means of the parallel or serial connection, an audio signal rich in overtones can be generated in each case.
