ABSTRACT:
A signal processing circuit outputs a signal corresponding to a quality of a digitized input signal. An edge counter of the signal processing circuit counts the number of times the input signal rises and/or falls in a predetermined period. An output unit of the signal processing circuit outputs a signal representing the number of times counted by the edge counter. This signal is output as the signal corresponding to the quality of the input signal.
