ABSTRACT:
An information-discriminating circuit has a biasing device that superposes bias voltage on an input signal, and a comparator that discriminates information by comparing an output signal from the biasing device with a threshold value. The difference between the bias voltage and the threshold value is continuously adjusted such that a noise margin is varied according to the amplitude of the input signal.
