Abstract

PURPOSE:To secure the switching between the FM stereo signal and the TV multiple aural signal by detecting the subchannel signal contained in the TV multiple aural signal. CONSTITUTION:In case the FM-detected signal emerging at the output of tuner 2 is the TV aural signal, the subchannel signal contained in the multiple aural composite signal is detected through the detector circuit. And this output turns on and off each switch circuit. Thus the multiple aural signal is applied to multiple aural demodulator circuit 7 and then demodulated to be applied to low frequency signal systems 8 and 9. Then with output of the stereo composite signal through tuner 2, switch circuits 4 and 5 are turned off since no stereo composite signal is detected at detector circuit 3. As a result, the stereo composite signal is applied to the stereodemodulator circuit for demodulation to deliver the right and left stereo signals. These stereo signals are applied to systems 8 and 9.
