Abstract
PURPOSE: To ensure the reception over a wide range of frequency by varying the division ratio of the divider to change the contents of the channel selection counter, memorizing previously the contents of the channel selection counter of the receivable broadcast station and then reading and displaying the contents of the memory.
CONSTITUTION: Channel selection counter 14 is provided to count the output of the channel selection pulse generator, along with 1/N divider 9 whose division ratio is controlled by the output of counter 14 plus frequency comparator 10 which gives a comparison to the output phase between reference oscillator 11 and divider 9. Thus the PLL circuit is formed to control the frequency of the local osicllator of front end 1 by the output of comparator 10. Then the contents of counter 14 is changed by the control of control part CTL, and then varying division ratio N of divider 9 to detect the receivable broadcast station. The contents of counter 14 corresponding to the receivable broadcast station is memorized in memories 59N and 59P via binary-decimal decoder 20, and then the contents of these memories are read out through part CTL to be displayed to plane display device 47.
