Description

Anordnung zur Umwandlung einer höheren Frequenz in eine niedrigere. Es ist bekannt, mittels Spulen mit Eisenkern eine Frequenzvervielfachung zu erzielen. Der Gegenstand der vorliegenden Erfindung besteht nun darin, eine höhere Frequenz in eine niedrigere umzuformen, wobei ebenfalls Eisentransformatoren verwendet werden. Um die Umwandlung einer .höheren Frequenz in eine niedrigere zu erreichen, ist es erforderlich, an den Eisenkern Schwingungskreise anzuschalten, die so dimensioniert sind, daB die Eigenfrequenzen aller Kreise in einer linearen Abhängigkeit stehen. Der einfachste Fall dieser Art ist der, daß die Summe der beiden erregten` Frequenzen w1 und w2 gleich der erregenden Frequenz w ist. ü)1+ w2 - w. Eine allgemeine Schaltung zeigt Abb. i. Der Generator arbeitet auf den einen Kreis mit der Frequenz w, in den beiden anderen Kreisen entstehen die Frequenzen w, und w2, sobald die Kreise auf diese Frequenzen abgestimmt werden und dem Eisenkern noch eine Vormagnetisierung erteilt wird. Auch ohne Vormagnetisierung sind solche Frequenzen möglich, wenn die Beziehung besteht w1 -@- 2 (J2 = w, es findet jedoch kein selbständiges Anschwingen statt.Arrangement for converting a higher frequency into a lower one. It is known to achieve a frequency multiplication by means of coils with an iron core. The object of the present invention now consists in converting a higher frequency into a lower one, iron transformers also being used. In order to convert a higher frequency into a lower one, it is necessary to connect oscillation circuits to the iron core, which are dimensioned in such a way that the natural frequencies of all circuits are linearly dependent. The simplest case of this kind is that the sum of the two excited 'frequencies w1 and w2 is equal to the exciting frequency w. ü) 1+ w2 - w. A general circuit is shown in Fig. i. The generator works on one circuit with the frequency w, the frequencies w and w2 arise in the other two circles as soon as the circles are tuned to these frequencies and the iron core is given a premagnetization. Such frequencies are also possible without pre-magnetization, if the relationship is w1 - @ - 2 (J2 = w, but there is no independent oscillation.

Anwendungsmöglichkeiten ergeben sich, sobald w,, in der Nähe der Erregerfrequenz w liegt, mit dieser Schwebungen bildend, so daß w2 die Frequenz der Schwebungsperiode annimmt. Für diesen Fall kann eine Vereinfachung der Schaltung vorgenommen werden, indem die Kreise der Frequenzen w und w1 in einen zusammengelegt werden, und der Generator auf einen verstimmten Kreis arbeitet (Abb. 2). Ist der Generator ein Röhrensender, so muß auf Schaltung i zurückgegriffen werden, weil dieser nur ' eine Eigenschwingung des Systems anregt. Werden die Kreise der Frequenzen w1 und w2 in Abb. i -in einen Kreis zusammengelegt, so haben Versuche ergeben, daß eine Halbierung der Generatorfrequenz stattfindet.Possible applications arise as soon as w ,, is close to the excitation frequency w lies, forming beats with this, so that w2 is the frequency of the beat period accepts. In this case, the circuit can be simplified, by merging the circles of frequencies w and w1 into one, and the Generator works on a detuned circuit (Fig. 2). If the generator is a tube transmitter, so you have to fall back on circuit i, because this only 'one natural oscillation of the system. Become the circles of frequencies w1 and w2 in Fig. I -in one Combined circle, experiments have shown that the generator frequency is halved takes place.
