Abstract

PURPOSE:To suppress the increment of a sliding noise without allowing reversal easy to generate by providing a correction circuit to change the frequency characteristic of a regenerative signal based on the detection output of temperature or humidity. CONSTITUTION:Since the sliding noise is increased according to temperature rise or humidity reduction, a temperature or humidity sensor 6 and an (f)- characteristic correction circuit 5 are provided in the circuit of the regenerative signal. When the temperature rise or the humidity reduction is detected with the sensor 6 in such constitution, the sliding noise is decreased by attenuating characteristic centering a frequency 7MHz with the (f)-characteristic correction circuit 5 based on the detection signal. Also, it is caused by a reason that the frequency in the vicinity of 7MHz corresponds to the upper side band component of an FM luminance signal and the remarkable reduction of the component tends to generate easy reversal to prohibit the attenuation of the characteristic in an ordinary operation.
