<p>A television receiver includes a correction filter (10) having an inclination characteristic opposite to a slope of a video intermediate frequency signal. The video intermediate frequency signal corrected by the correction filter is applied to a PLL circuit (11) and the PLL circuit generates a carrier signal of a video intermediate frequency locked to the video intermediate frequency signal. A synchronous detecting circuit (16) detects the video intermediate frequency signal before the correction in response to the signal outputted from the PLL circuit and outputs a video signal. At the same time, it generates a sound FM signal corresponding to a beat of the carrier signal of the video intermediate frequency and a carrier signal of a sound intermediate frequency. A sound detecting circuit (20) detects the sound FM signal and outputs a sound signal.</p> |
