Circuit for volume compression and/or expansion of a signal

摘要

Circuit for amplitude compression and/or expansion of an AF signal with a field effect transistor (7) whose gate is connected to the output of a control voltage generator (10) and to the signal path (1-6). According to the invention, the gate is connected via a resistor (8) to a low-impedance output (a) of an amplifier (2) disposed in the signal path. Optimum decoupling between the signal (NF) and the control voltage (UR) is thereby achieved and interference with the signal by the control voltage avoided. <IMAGE>
