Abstract
A device for discriminating between two values of a signal using DC offset compensation including an automatic gain control circuit, a peak detector circuit and a feedback path from the peak detector circuit to the input circuit of the automatic gain control circuit. The value of the feedback current is regulated so that the maximum value of one of the same polarity signals and the opposite polarity signal coincides with the minimum value of the other of the two signals.
