Abstract

PURPOSE: To assure the high-accuracy reception by giving the correction to the division ratio of the programable divider in accordance with the detection extent of the frequency fluctuation to the detection output and then giving the correction to the fluctuation of the frequency.
CONSTITUTION: Control circuit 7 is provided to set division ratio N of programable divider 3 which is a component element of the PLL forming local oscillating circuit 1 of the radio receiver. Thus in case some fluctuation is caused to the intermediate frequency by some cause during reception of the broadcast, the addition and the subtraction is carried out at arithmetic circuit 8 between the data of the 2nd register 10 and constant data "1" given from ROM13 by control signals S1 and S2 supplied from frequency fluctuation detecting circuit 15. And this calculation result is transferred to register 10 via the 1st register 9 to receive the ±1 operation again with the data of register 10. As a result, the division retio of divider 3 increases or decreases by 1. In other words, local oscillation frequency f0 receives the fine adjustment in the unit of 1kHz. Thus the ± operation is continued until the fluctuation of the frequency becomes zero to give the correction to the fluctuation at all times during the reception.
