Abstract

PURPOSE:To obtain a detection circuit of low cost, by comparing the phase of a 1H synchronizing fH signal generated by the VCO circuit in the AFC circuit, and a horizontal synchronizing signal whose skew has been compensated, used as a synchronizing signal of the VCO circuit. CONSTITUTION:An FM signal of the luminance signal system, which has been output through the band pass filter 13 is input to the FM demodulator 14 after the skew has been compensated, and the demodulated luminance signal is made to pass through the horizontal synchronizing separator circuit 15, and a horizontal synchronizing signal is obtained. This horizontal synchronizing signal becomes an input signal to be provided to the phase detection circuit 26 for AFC, and the phase comparator 27. On the other hand, a dividing fH signal is output from the 1/N frequency divider 25 to which an output of the VCO circuit 25 for AFC is input, and this signal is used as both an input of the phase detection circuit 26 for AFC, and an input signal of the phase comparator 27. And a skew detecting pulse can be obtained from the phase comparator 27.
