Abstract

A circuit arrangement for adjusting the amplification of the signals of several channels, at the same value characterized in that: a controlled switch (s1 ... Sn) and a bandpass filter (bp1 .... Bpn) are introduced in each channel (1 ... N) for the common control of the switches (s1 ... Sn) a square wave generator is connected to the switches (s1 ... Sn) through an integrator (ig), the first input of an adder circuit (add) and a threshold circuit (sch); a control potential (ur) is applied to the second input of the adder circuit (add), with the control potential margin (ur), the integrator output amplitude (ig) and the threshold potential value (sw) of the threshold circuit (sch) being balanced in such a way that the switches (s1 ... Sn) can be operated with an arbitrary duty cycle. (Machine-translation by Google Translate, not legally binding)
