Abstract

PURPOSE:To remove unneeded pulses by inputting the output digital input signal of a delay time setting circuit to FF, by inputting its output to a coincidence circuit together with the digital input signal, and by inputting its output to the reset terminal of the delay time setting circuit. CONSTITUTION:The n-scale counter 2 has input terminal CP1 and output terminal Qn and its output is sent to FF4 via count select switch 3. On the other hand, FF4 receives the output pulse and digital input signal of counter 2, and its output and digital input signal are inputted to coincidence circuit 7, whose output is led to reset terminal R of counter 2. Then, the output waveform of FF4 is delayed fixed time behind the digital input waveform, so that the simple constitution can remove unneeded pulses.
