1. Schaltungsanordnung zur Regelung einer Verstärkerstufe mit Serien/Serien-Gegenkopplungunter Verwendung von steuerbaren Widerständen, die den Gegenkopplungsgrad der Verstärkerstufe bestimmen, dadurch gekennzeichnet, dass zwischen den Ausgangselektroden (1,2) des eigentli-   chen Verstärkerelementes   (T) die Diagonale einer Brücke liegt, die aus vier spannungsgesteuerten   Widerständen besteht, wobei der zweiten Brückendiagonale eine veränderbare   Steuerspannung (Ust) derart zugeführt wird,

   dass bei Maximalverstärkung der Gegenkopplungswiderstand und bei Minimalverstärkung der Lastkreiswiderstand durch entsprechende Brückenzweige überbrückt wird.

   and PATENT CLAIMS:
1. Circuit arrangement for regulating an amplifier stage with series / series negative feedback using controllable resistors which determine the degree of negative feedback of the amplifier stage, characterized in that the diagonal of a bridge lies between the output electrodes (1,2) of the actual amplifier element (T) , which consists of four voltage-controlled resistors, the second bridge diagonal being supplied with a variable control voltage (Ust)

   that with maximum gain the negative feedback resistance and with minimum gain the load circuit resistance is bridged by appropriate bridge arms.
