Abstract
A digital circuit for controlling the gain of an amplifier stage of a coded signal receiving channel is provided. The circuit includes a peak detector coupled to the input terminal of the receiving channel through a coded signal rectifying circuit and a gain control stage. The gain control stage includes a digital comparator having two input terminals respectively connected to an output terminal of the peak detector and to a memory, and an output terminal coupled to a gain control terminal of the amplifier stage. The address selectable contents of the memory contain predetermined peak values in coded form.
