ABSTRACT:
In a circuit system for the generation of a direct control voltage dependent upon an alternating voltage for a dynamic compander device, the system including a charging capacitor, a charging circuit connected to charge the capacitor, and a circuit connected to discharge the capacitor, a comparator unit is connected to effect comparison between the alternating voltage and a reference voltage and to produce an output voltage representative of the amount by which the alternating voltage exceeds the reference voltage, and at least one of the circuits is formed of a current source and an electronically controllable current path connected between the source and the capacitor and having a control input connected to the comparator unit for varying the conductance of the current path as a function of the output voltage of the comparator unit.
