Abstract

PURPOSE:To enable a correct control pulse to be generated by differentiating a horizontal flyback pulse and narrowing the pulse width of it. CONSTITUTION:The horizontal flyback pulse is differentiated and a first transition pulse of it is made to be a square wave. By using a last transition pulse obtained by differentiating that pulse, the last transition pulse obtained by differentiating a horizontal synchronizing pulse is gated. That means, as transistors 22 and 23 constitute an NAND gate, the collector of a transistor 26 obtains a wave form (g) which only the common term of the two pulses turn on and this pulse drives a pedestal clamp circuit 27 and a burst gate pulse 28. Thus, even when the width of the last transition pulse obtained by differentiating the horizontal synchronizing pulse is extended by dispersion, the pulse width can be prevented being extended and the correct control pulse can be generated.
