Abstract
PURPOSE:To prevent the fetching of erroneous correction data which is apt to occur due to the degradation in reception state, by detecting the multipath disturbance of a reception broadcast wave and inhibiting the fetching of demodulated data during the generation of this detection output. CONSTITUTION:The detection output of a multipath detecting circuit 18 which detects the multipath disturbance of the reception broadcast wave based on the FM detection output is supplied to a controller 14, and a switch circuit 17 is opened while the multipath disturbance occurs. Since the supply of demodulated data and a clock to a group and block synchronizing and error detecting circuit 12 is stopped then, data is inhibited from being fetched to the controller 14 while the multipath disturbance occurs. Thus, the fetching of erroneous data is prevented in case of erroneous error correction due to the degradation in reception state accompanied with the occurrence of the multipath disturbance.
