Radio receiver
A radio receiver includes a noise canceller (2) for removing a pulse noise from a composite signal from an FM detection circuit (1), a stereo demodulation circuit (3) for demodulating the output signal of the noise canceller (2) to reproduce a stereo signal, and a VCO (21) for outputting a clock sig...

Summary: | A radio receiver includes a noise canceller (2) for removing a pulse noise from a composite signal from an FM detection circuit (1), a stereo demodulation circuit (3) for demodulating the output signal of the noise canceller (2) to reproduce a stereo signal, and a VCO (21) for outputting a clock signal as an origin of a clock signal used in the stereo demodulation circuit (3). A clock signal used in a CCD (15) of the noise canceller (2) is generated based on a clock signal output from the VCO (21), so as to synchronize the phase of the signal used in the CCD (15) with the phase of the clock signal used in the stereo demodulation circuit (3), thereby suppressing generation of a beat signal in the output of the stereo demodulation circuit (3). |
