PURPOSE:To provide a waveform equalizer capable of executing optimum waveform equalization even in the case that a cable television broadcast is received. CONSTITUTION:In the case that received contents are to be changed while the cable television broadcast is received, channel selection is executed by a converter 304. The converter 304 outputs a new program instead of the program thus far in conformity with the channel selection information. At that time, since the channel is changed, the discontiuity of a signal occurs in the output of the converter 304. A discontinuity detection circuit 102 detects this discontinuity, and outputs a discontinuity detection signal. By the input of the discontinuity detection signal, a waveform equalization circuit 104 is initialized, and a sound multiplex demodulation circuit 110 mutes a sound signal.
