Abstract

PURPOSE: To simplify the tuning operation by detecting the video signals from the IF signals via the video detection circuit, actuating the muting circuit by the output of the video signal through the OR circuit and giving the tuning display only when the video signal tunes to the aural signal.
CONSTITUTION: Tuner 2 can receive only the aural signals of the TV broadcast, and the output of tuner 2 is IF-converted via local oscillator 4 and mixer ciruit 3. Then the IF signals are processed at least through FM detection circuit 7, muting circuit 9 and low frequency amplifier circuit 10 each to sound the speaker. The video signals are detected from the IF signals through video detection circuit 13, and circuit 9 is acturated by the detection signal and through OR circuit 16. As a result, no noise is produced and no tuning indication is given via the muting function in case a tuning is given to the video signal or other erroneous signals, and the tuning display is given only when a tuning is secured to the aural signal. Thus, the tuning operation can be simplified greatly.
