Abstract
PURPOSE: To ensure the channel selection over a wide range of frequency by varying the division ratio of the frequency divider of the FM receiver via the frequency division technique and thus changing the frequency of the front end as well as memorizing the division ratio corresponding to the receivable broadcast station into the memory.
CONSTITUTION: Channel selection counter 14 is provided to count the output of the channel selection pulse generation circuit, along with 1/N divider 9 whose division ratio N is controlled by the output of counter 14. At the same time, reference oscillator 11, frequency phase comparator 10 to give a comparison to the phase of the output of divider 9, and the PLL circuit to control the frequency of the local oscillator of front end 1 by the output of comparator 10 are formed respectively. Then the contents of counter 14 is changed by the control of control part CTL, and thus the division ratio of divider 9 is varied. Then the channel selection for the receiving broadcast station is detected via FM demodulator 3 and stereo demodulator 5. With this detection output, the contents of counter 14 corresponding to the receivable broadcast station is memorized in nonvolatile memories 49N and 49P via matrix decoder 24.
