Technical Examples

An AM receiver circuit comprises an IF intensity detection section which detects intensity of a carrier wave of an IF signal and outputs an IF signal carrier wave intensity signal in accordance with the detected intensity. The IF intensity detection section extracts the carrier wave frequency component of the IF signal using a BPF, and converts the extracted intensity of the IF signal carrier wave intensity into a direct current signal using an integrator, to thereby obtain the IF signal carrier wave intensity signal. A sound compensation section, which serves to compensate sound quality of an audio signal output from an AM detection section, performs sound quality compensation based on the IF signal carrier wave intensity signal when the received field intensity is low. In this manner, appropriate sound quality compensation can be performed even when the received broadcast wave field intensity is low.
