Description

Verfahren zur Abstimmanzeige für Empfänger mit Braunscher Röhre In vielen Fällen ist die richtige. Abstimmung eines Empfangsgerätes nicht ohne weiteres aus dem empfangenen Signal zu erkennen. Bei einfachen Empfängern dient als. Kriterium der richtigen Abstimmung beispielsweise das Maximum der Lautstärke. Bei automatischem Schwundausgleich versagt jedoch dieses Verfahren, man muß zu anderen Mitteln greifen. Man verwendet dann ein Meßinstrument in Gestalt eines Milliamperemeters, magischen. Auges, einer Glimmröhre od. dgl.Procedure for tuning display for receivers with Braunscher tube In many cases is the correct one. Tuning a receiving device is not easy can be recognized from the received signal. For simple recipients it serves as a. criteria correct adjustment, for example, the maximum volume. With automatic However, this method fails to compensate for shrinkage, so other means have to be used. A measuring instrument in the form of a milliammeter, magical, is then used. Eye, a glow tube or the like.

Alle diese Möglichkeiten. sind nicht anwendbar, wenn das Auge anderweitig in Anspruch genommen ist, wie z. B. beim Fernsehen oder beim Impulsempfang u. dgl.All of these options. are not applicable if the eye is otherwise is used, such. B. when watching TV or receiving impulses and the like.

Beim Fernsehen, hei Impulsempfang und in ähnlichen Fällen wird das empfangene Signal ebenfalls sichtbar gemacht. Das Auge der Bedienungsperson ist dann schon für die Beobachtung des Empfangssignals in Anspruch genommen, so daß, die gleichzeitige Überwachung eines Abstimmanzeigers nicht ohne weiteres möglich ist.With television, with impulse reception and in similar cases this is received signal also made visible. The operator's eye is then already used for the observation of the received signal, so that, the simultaneous monitoring of a voting indicator is not easily possible is.

Man kann diesen Schwierigkeiten natürlich aus dem Wege gehen, indem man die richtige Abstimmung akustisch anzeigt, z. B. durch einen Ton, der bei falscher Abstimmung hörbar wird oder seine Tonhöhe in Abhängigkeit von der Abstimmung ändert.One can of course avoid these difficulties by the correct vote is indicated acoustically, e.g. B. by a sound that is wrong Vote becomes audible or changes its pitch depending on the vote.

Eine derartige Lösung ist aber nicht möglich, wenn gleichzeitig Hörempfang gemacht werden soll. Außerdem entsteht ein erheblicher Mehraufwand durch diese zusätzliche Einrichtung: Die Erfindung stellt nun einen Weg dar, auf dem es trotzdem möglich ist, die Abstimmanzeige und rli:P RPnharhtn",io .rlrc 'itOlnala alP.irh7@Plitioa cnr71inehmen. Es wird erfindungsgemäß vorgeschlagen, das: Empfangssignal und die Ab;stimmanzeige so . zu koppeln, daß nur bei richtiger Abstimmung eine einwandfreie Beobachtung möglich ist.However, such a solution is not possible if listening is being received at the same time should be made. In addition, this additional work creates a considerable additional expense Facility: The invention now represents a way in which it is still possible is, the voting display and rli: P RPnharhtn ", io .rlrc 'itOlnala alP.irh7@Plitioa cnr71 According to the invention, it is proposed that: received signal and the voting display like that. to couple that only with correct coordination a flawless Observation is possible.

Hierzu stehen mehrere Wege offen, z. B. kann man den Strom der Kathodenstrahlröhre mit -einer Gleichspannung steuern, die derart von der Abstimmung des Empfangsgerätes abhängig ist, daß die Kathodenstrahlröhre, nur bei richtiger Abstimmung hell gesteuert wird.There are several ways to do this, e.g. B. one can see the current of the cathode ray tube -control with a DC voltage, which is so from the vote of the receiving device depends on the fact that the cathode ray tube is brightly controlled only with the right coordination will.

Ferner kann man an die Platten bzw. die Ablenkspulen der Kathodenstrahlröhre zusätzlich zur Ablenkspannung eine Gleichspannung legen, die von der Abstimmung des Empfängers abhängig ist, so daß bei falscher Abstimmung das Bild aus der Mittellage verschoben wird. In diesem Falle kann gleichzeitig die Richtung angezeigt werden, in welcher nachgestimmt werden muß. Wenn z. B. das Bild; auf dem Schirm der Braunschen Röhre nach -. rechts wandert, muß der Empfänger auf höhere Frequenzen abgestimmt werden, wenn das Bild nach links wandert auf, tiefere.You can also access the plates or the deflection coils of the cathode ray tube In addition to the deflection voltage, apply a DC voltage that is determined by the vote of the receiver is dependent, so that in the event of a wrong adjustment the image from the central position is moved. In this case, the direction can be displayed at the same time in which must be retuned. If z. B. the picture; on the screen of the Braunschen Tube after -. moves to the right, the receiver must be tuned to higher frequencies when the image moves to the left, deeper.
