Abstract

PURPOSE:To improve circuit characteristics without causing mutual interference among BPF frequencies by separately supplying a video detection output to two sound intermediate-frequency circuit systems. CONSTITUTION:A detection output from output terminal 21B of video detector 21 is supplied to BPF 26 to derive a sound intermediate-frequency signal, which is amplitude-limited by FM demodulator 27 and FM-detected. This detection output is de-emphasized by de-emphasis circuit 28 and an audio frequency signal, the subsound signal of different broadcast, is led to output terminal 29. On the other hand, a detection output from output terminal 21A of detector 21 is similarly passed through BPF22, FM demodulator 23 and the de-emphasis circuit to send an audio- frequency signal, the main sound signal of the different broadcast, to output terminal 25. In stereophonic mode, outputs of terminals 25 and 29 are reproduced by being processed by a matrix circuit. Further, the detection output of terminal 21A of detector 21 has a sound intermediate-frequency signal trapped by trap circuits 30 and 31 and a reproduced video signal is outputted to output terminal 32.
