Abstract

PURPOSE:To execute the channel selection easily and also swiftly when it is executed by means of manual sweep, by executing both the manual sweep by the shift mode and the manual sweep by the step mode, in the synthesizer receiver. CONSTITUTION:The output of the channel selection pulse generating circuit CTL is counted by the channel selection counter 14, and the frequency dividing ratio N of the frequency divider 9 is controlled by this output. The output which has divided the output of the local oscillator 1 by the 1/N frequency divider is compared in terms of phase by the phase comparator circuit 10, and the local oscillator 1 is controlled. And, the contents of the channel selection counter 14 are changed by the output of the channel selection pulse generating circuit CTL, the frequency dividing ratio of the 1/N frequency divider 9 is varied so that a desired broadcasting station can be received, and also both the means for changing the contents of the channel selection counter 14 by 1 counting value, and the means for varying the counting value continuously are provided on the channel selection pulse generating circuit CTL, by which manual sweep is executed.
