Abstract

PURPOSE:To attain reception that corresponds to detrioration in magnetic field instensity during the reception by putting a noise reducing circuit into operation in accordance with the output of an automatic tuning control circuit. CONSTITUTION:Once receiving a radio wave, the conventional tuning mechanism equipped with an automatic tuning control circuit can hardly attain tuning again even if the radio wave weakens. However, when the receiver is moved or put in fading mode, output (a) of tuning control circuit 7 also decreases. The stereophonic demodulating circuit is controlled by detecting the decrease in output (a) through inverter 11, and consequently stereohphonic demodulating circuit 3 is forced to switch to the monaural mode to prevent S/N from deteriorating. Further, high- blending circuit 16 is put into operation in accordance with the decrease in electric- field intensity to improve S/N of a demodulated signal.
