Figure 1 shows horizontal synchronization A according to an embodiment of this invention.
2 is a waveform diagram showing the shaping state of the flyback pulse waveform in the horizontal synchronous AFC circuit of FIG. 1. FIG. 3 is a block diagram showing the conventional horizontal synchronous AFC circuit. FIG. 4 is a block diagram showing the FC circuit. is a timing chart in a conventional horizontal synchronous AFC circuit. In the figure, 1 is a flyback pulse, 2 is a horizontal synchronizing signal, 3 is an AFC, 7 is a Zener diode, R 1 to R 3 are resistors, and C 1 to C 3 are capacitors. In addition, in the figures, the same reference numerals indicate the same or equivalent parts.
