Abstract

PURPOSE:To eliminate jitter generated on a TV picture, by independently feedback-controlling a reset operation of a binary counting circuit by obtaining a set signal by its own timing and a feedback line. CONSTITUTION:A clock signal of prescribed frequency sent from a main oscillator 6 and a frequency-divider 8 is applied to a binary counting circuit 1 through an input line 30. In a skipping circuit 10, when a set signal of a logical value ''1'' is applied from an input line and is set, a logical value ''0'' is provided to a gate 9 of OR from an output line 31 of an opposite logical side Q, therefore, a horizontal synchronizing negative pulse provided to an output line 72 from a synchronizing signal generator 7 resets the circuit 1 through the gate 9. Subsequently, when signals of output lines 21, 22, 24, 26, 27 and 29 of the circuit 1, and a clock signal of an input line 30 are inputted to a NAND gate 5, a negative pulse is outputted to an output line 51. This negative pulse sets the circuit 1 from an input line 92 through a gate 4.
