Abstract
PURPOSE:To attain high performance, by changing the oscillating frequency of a digital voltage controlled oscillator in response to the change in the oscillating frequency of an analog frequency synthesizer so as to perform demodulation without any hindrance. CONSTITUTION:When an oscillated frequency of an analog synthesizer 8 is increased by an output from a control circuit 10, the intermediate frequency is varied and noise is eliminated. On the other hand, the oscillated frequency of a digital voltage controlled oscillator 11 is controlled by the control circuit 10 and varied corresponding to the frequency being the result of the change in the oscillated frequency of the analog frequency synthesizer to perform the demodulation of an SSB signal without any hindrance.
