ABSTRACT:
A signal processing circuit includes a signal selecting device operative for selecting and outputting one of plural input signals. A filter connected to the signal selecting device filters the signal selected by the signal selecting device with a changeable center frequency of a pass band of the filtering. A frequency changing device is operative for temporarily changing the center frequency when the signal selected by the signal selecting device is changed from one to another. The filter includes, for example, a switched-capacitor filter.
