Abstract

PURPOSE:To digitally demodulate a composite signal by using a multiplexing circuit to demodulate respective signals of an FM stereo and a TV sound multiplexing in common. CONSTITUTION:An IF signal from an analog circuit part 1 is A/D-converted 8 and next, FM-detected 9. A digitally combined signal is demodulated by a multiplexing circuit 18. At the circuit 18, an FM stereoscopic broadcasting, etc., are demodulated by a circuit part 12, a TV voice multiplexing broadcasting, etc., are demodulated by a circuit part 13 respectively, a BPF 37 is used in common with circuit parts 12 and 13, and when it is used by the circuit part 12, and it is switched to a characteristic to separate a pilot signal from the FM stereoscopic broadcasting, etc., and when it is used by the circuit part 13, it is switched to a characteristic to separate a sub-carrier from a TV broadcasting, etc., by a controller 17, respectively.
