PROBLEM TO BE SOLVED: To provide a receiver that is downsized with weight reduction and can receive an FM radio broadcast signal in addition to the reception of a television broadcast signal. SOLUTION: The receiver is provided with a tuner 12 that converts a received FM radio broadcast signal into the same intermediate frequency signal as an audio intermediate frequency carrier signal at the reception of a television broadcast signal and provides an output in the case of receiving the FM radio broadcast signal, a SAW filter 13 that makes the intermediate frequency band signal pass that is outputted from the tuner 12, a video detector 15 that uses a video intermediate frequency carrier signal fo outputted from a VCO 17 at the reception of the television broadcast signal to detect a video signal including an audio subcarrier wave signal fs and uses the self-running oscillation signal fo outputted from the VCO 17 at the reception of the FM radio broadcast signal to detect the audio subcarrier wave signal fs, a VIF AGC circuit 15 that makes the amplitude of a video signal constant, and an AGC circuit 41 that makes the amplitude of the audio subcarrier wave signal fs constant. |
