Abstract

A circuit arrangement includes two adjustable amplification devices where the signal output of the first amplification device is connected to the signal input of the second amplification device. The first amplification device has a digital input for controlling its gain and the second amplification device has an input for controlling its gain. The input for gain control in the second amplification device is connected to the input for controlling the gain of the first amplification device via a means such that a change in the gain of the second amplification device in one direction is effected by a change in gain, brought about by means of the control, in the first amplification device in the opposite direction such that the total gain remains essentially the same.
