Description

Die Erfindung bezieht sich auf eine Liiiearisierung von Kennlinien bei Gegentaktschaltungen, die miteinander derart kombiniert werden, daß die eine Kennlinie die andere fortsetzt. An der Stelle, an der die beiden Kennlinien zusammenstoßen, ergab sich bisher immer eine h; ichtlinearität.The invention relates to a linearization of characteristic curves in push-pull circuits that are combined with one another in such a way that the one Characteristic that continues the other. At the point where the two characteristics meet, so far there has always been an h; non-linearity.

Erfindungsgemäß wird die Kennlinie einer Gegentaktschaltung in der Überlappungszone dadurch linearisiert, daß den Gittern der Gegentaktanordnung eine im Verhältnis zur Frequenz der Signalspannung hohe Frequenz überlagert wird. Hierdurch tritt eine Linearisierungswirkung bezüglich der Kennlinie bzw. der beiden Kennlinien an der Stelle auf, an der sich die beiden Kennlinien aneinandersetzen. Diese Linearisierungswirkung ist der Linearisierung von Tonaufzeichnungen auf Magnettonträgern ähnlich, die unter Anwendung einerHochfrequenzüberlagerung vorgenommen wird. Hochfrequenzüberlagerungen bei Gegentaktschaltungen im Sinne der Erfindung sind bisher jedoch noch nicht durchgeführt worden.According to the invention, the characteristic of a push-pull circuit in the Overlap zone linearized in that the grids of the push-pull arrangement a high frequency is superimposed in relation to the frequency of the signal voltage. Through this a linearization effect occurs with regard to the characteristic curve or the two characteristic curves at the point where the two characteristics meet. This linearization effect is similar to the linearization of sound recordings on magnetic sound carriers, which is described under Application of a high frequency superposition is made. High frequency overlays in push-pull circuits within the meaning of the invention, however, have not yet been carried out been.

In der Zeichnung ist eine Ausführungsform nach der Erfindung beispielsweise dargestellt.In the drawing, an embodiment according to the invention is for example shown.

Fig. i zeigt eine Gegentaktschaltung an sich üblicher Art, bestehend aus zwei Röhren i und 2, deren Gitter an den Enden einer geteilten Übertragersekundärwicklung 3 liegen. Erfindungsgemäß ist in die gemeinsame Gitterzuleitung ein Hoch: frequenzgeneratorHF gelegt, dessen Frequenz hoch im Vergleich zur Signalfrequenz ist. Anodenseitig hebt sich die Hochfrequenz infolge der Gegentaktschaltung wieder heraus. Gegebenenfalls können auch, unter Umständen zusätzlich, Mittel zur Dämpfung der Hochfrequenz vorgesehen sein. Diese Mittel sind durch einen Kondensator q. angedeutet.Fig. I shows a push-pull circuit of a conventional type, consisting from two tubes i and 2, the grids of which at the ends of a split transformer secondary winding 3 lie. According to the invention, a high frequency generator HF is in the common grid feed line placed whose frequency is high compared to the signal frequency. Lifts on the anode side the high frequency emerges again as a result of the push-pull circuit. Possibly Means for damping the high frequency can also be provided, possibly in addition be. These means are through a capacitor q. indicated.

In Fig.2 ist der Verlauf der beiden zu den Röhren i und -2 gehörenden Kennlinien K, und K, dargestellt. Durch Überlagerung der Hochfrequenz entsteht an der Stoßzone der beiden Kennlinien ein Spannungsverlauf, wie er durch die Kurve 5 angedeutet ist. Die Kurve 5 bedeutet die Signalfrequenz, der ein Hochfrequenzträger überlagert ist. Durch die Hochfrequenzüberlagerung entsteht in dem fraglichen Gebiet eine Linearisierung der Kurve, die durch die gestrichelten Grade 7 angedeutet ist.In Fig.2 is the course of the two belonging to the tubes i and -2 Characteristic curves K and K shown. Due to the superposition of the high frequency, an the impact zone of the two characteristics has a voltage curve, as shown by the curve 5 is indicated. The curve 5 indicates the signal frequency, which is a high frequency carrier is superimposed. The high-frequency superposition occurs in the area in question a linearization of the curve, which is indicated by the dashed degrees 7.
