Abstract

A transmission circuit arrangement for reversing the polarity of a signal, characterized in that the input signal is applied to the base of a junction transistor, while the output signal is derived from an impedance in the collector circuit of said junction. transistor and why the arrangement comprises means for varying the bias voltage of the collector-base junction between a level at which said collector-base junction is biased so strongly in the direction of cut that the transistor operates as an inverter-amplifier and a level at which said junction is polarized so strongly in the forward direction of the voltage at the collector electrode is almost the same and is in phase with the voltage at the base electrode.
