A demodulator is able to demodulate a television signal and an FM broadcast signal by a common demodulator. Also, a receiver is able to output television video signal and audio signal and an audio signal of the FM broadcast signal by the common demodulator without using a second mixer for frequency-converting the FM broadcast signal to provide an audio intermediate frequency signal of 10.7 MHz when the FM broadcast signal is received. A demodulator includes a first input terminal, a second input terminal, a third input terminal and a change-over switch and wherein the change-over switch connects the first input terminal, a video detector and a video carrier generator to receive the television signal and the change-over switch connects the third input terminal, the video detector and the video carrier generator to receive the FM broadcast signal.
