Abstract: PURPOSE:To stabilize the output of the automatic frequency control AFT circuit by controlling the carrier frequency of a signal to be processed while receiving the output of a removing circuit which removes the modulated component of a carrier modulated by the signal to be processed. CONSTITUTION:A slice circuit 2 executes a slice processing to the signal at the degree of removing the component modulated by a video signal from this signal while receiving the video carrier signal applied from a video intermediate frequency amplifier circuit 1 as a differential output, and applies the signal to an AFT circuit 3. The circuit 3 amplifies the signal applied from the circuit 2 at a limiter amplifier 4 and fixes the amplitude. A detection circuit 5 detects the output signal of the amplifier 4 under the control of a phase shift circuit 6, which shifts the phase at 90 deg. with this output signal as the input, and the change of a video intermediate frequency is extracted as the change of a DC voltage. Thus, even when the carrier of the output signal from the circuit 1 is modulated by the video signal, the output fluctuation of the circuit 3 caused by this modulation can be controlled and stabilized.
