Abstract
PURPOSE:To accurately decide a wave state and to perform an appropriate noise reduction processing by detecting the number of times of switching of an antenna within a prescribed time, and deciding it as the defect of the wave state when the number of times of switching exceeds a prescribed value. CONSTITUTION:The number of times of switching of the antenna within the prescribed time is detected by a switching number detecting means 15, and when it exceeds the prescribed value, it is decided as the defect of the wave state by a wave state decision means 16. And as the noise reduction processing, for example, a command signal to operate an automatic tone control circuit 14 and an automatic separation control circuit 13 is outputted. In such a way, broadcasting is switched from stereoscopic broadcasting to monophonic broadcasting by the operation of the automatic separation control circuit 13, and a signal after FM detection is corrected to a flat characteristic, and also, the highpass of a frequency characteristic in a low frequency amplifier circuit is attenuated by the operation of the automatic tone control circuit 14, then, the noise is reduced.
