PURPOSE:To obtain pulse outputs of fixed time width by continuing output of specified state of a flip-flop for a period determined by a specific number of clock pulses that passed an inhibit circuit. CONSTITUTION:Clock pulse are inputted to a counter 12 through an inhibit circuit 11 and output 13 of the counter 12 is inputted to the reset terminal of an RS type flip-flop 15. Output 16 of the flip-flop 15 is outputted as output pulse of the circuit, and at the same time, acts as a control signal 16a of an inhibit circuit 13. When output 16 of the flip-flop 15 is 'H', the inhibit circuit 11 passes the clock pulse, and checks when the output is 'L'. As the period in which output 16 is 'H' corresponds to a period in which specified number of clock pulses are inputted, the time can be determined exactly.
