Abstract
A radio-frequency signal receiver and its manufacturing method are disclosed. A tuner receives a radio-frequency signal, and a demodulator receives an output signal from the tuner. An error corrector receives an output from the demodulator. A determiner determines whether or not an error rate supplied from the error corrector is not less than a predetermined rate. A controller receives an output from the determiner, and based on the determination, the controller controls a plurality of sections forming the radio-frequency signal receiver. The controller controls selectively one of the plurality of sections, thereby lowering the error rate. A manufacturing method of this receiver makes a memory, coupled to the controller, store a shift-amount of frequency corresponding to an interference signal in a pass-band of a narrow-band filter.
