  • Apparatus and method for selecting station using D/A converter to control the local oscillator
    Patent number: 5628060
    Abstract: An apparatus and a method for selecting a station are disclosed in which a count section or a comparison section compares/decides a local oscillation frequency, and a digital/analog converter controls the local oscillation frequency according to the decided result, in order to perform an accurate and stable station selection. The apparatus includes a local oscillator means, a dividing means, a count section or comparison section, a control section, and a digital analog converter. The method includes the steps of controlling the digital/analog converter, dividing, the signal output from the local oscillator outputting correction data, and controlling increase/decrease of the oscillation frequency of the local oscillator according to the correction data.
