A first audio signal (L+R) is supplied to the VCO 24 so as to control its oscillation frequency f24. A second audio signal (L−R) is supplied to the VCO 14, so that an FM signal SSUB is formed whose occupied frequency band is outside the band of the first audio signal (L+R). This FM signal SSUB is supplied to an adder 26, hereby added to a phase comparison output that is supplied to a VCO 21 from a low-pass filter, and then supplied to the VCO 21.

摘要： A wireless receiver has an FM receiver for receiving an infrared radiation modulated by an audio signal. The received infrared radiation is demodulated into the audio signal, which is then supplied through a power amplifier to a loudspeaker unit or a headphone unit. The wireless receiver includes a detector for detecting whether or not the infrared radiation is received. An output signal from the detector is used to turn the power supply of the FM receiver and the power amplifier on or off. The user of the wireless receiver is not required to turn the receiver on and off manually.
