Abstract
PURPOSE: To ensure the reception over a wide range of frequency band by varying the division ratio of the divider of the receiving device incorporating the PLL circuit, altering the contents of the channel selection counter for memorization into the memory and then reading out the contents of the memory in sequence and via the control of the control part.
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 counter 14 plus phase frequency comparator 10 which gives a comparison to the output phase between divider 9 and reference oscillator 11. Thus the PLL circuit is formed to give the control to the frequency of the local oscillator of front end 1. Then the contents of counter 14 is varied by the control of control part CTL. Based on this varied contents, division ratio N of divider 9 is varied to then detect the receivable broadcast station via muting circuit 4 and the like. With this detection output, the receivable station is memorized in memories 49N and 49P. After this, the contents of these memories are read out in sequence through part CTL to realize reception in sequence for the receivable broadcast stations.
