ABSTRACT:
The invention relates to a circuit arrangement in a compander system for generating a direct control voltage which is dependent on an alternating voltage with the circuit arrangement including a time constant switch. The conductance determining the time constant in a charging current circuit is constantly varied in the transfer range in dependence on the voltage of a charging capacitor when a time constant switch takes place from one fixed value to a second fixed value.
