摘要：A radio-frequency signal receiver and its manufacturing method are disclosed. Atuner receives a radio-frequency signal, and a demodulator receives an output signalfrom the tuner. An error corrector receives an output from the modulator. A determinerdetermines whether or not an error rate supplied from the error corrector is not lessthan a predetermined rate. A controller receives an output from the determiner, andbased on the determination, the controller controls a plurality of sections forming theradio-frequency signal receiver. The controller controls selectively one of the plurality ofsections, thereby lowering the error rate. A manufacturing method of this receiver makesa memory, coupled to the controller, store a shift-amount of frequency corresponding toan interference signal in a pass-band of a narrow-band filter.
