 auftreten. Die Kondensatoren sind beispielsweise in die Gitterkreise eingeschaltet und beeinflussen die Verteilung der Wechselspannung in der Weise, wie bei der Schaltung nach Fig. 2 erläutert ist. Den Strecken Gitter-Kathode können auch hier definierte Widerstände parallel geschaltet werden. 



   PATENT-ANSPRÜCHE : 
 EMI2.1 
 ströme benutzten Schaltungen eine oder mehrere Kapazitäten Anwendung finden, die so abgeglichen sind, dass schnellere Frequenzen weniger und langsamere stärker geschwächt werden, um die Lautstärke der tieferen Frequenzen auf die der höheren und darüber hinaus   herabdrücken   zu können.

 occur. The capacitors are connected, for example, in the grid circles and influence the distribution of the alternating voltage in the manner as explained for the circuit according to FIG. Defined resistances can also be connected in parallel to the grid-cathode sections.



   PATENT CLAIMS:
 EMI2.1
 For the circuits used, one or more capacitances are used that are balanced in such a way that faster frequencies are weakened less and slower frequencies are weakened more so that the volume of the lower frequencies can be reduced to that of the higher and beyond.
