Abstract

PURPOSE:To obtain a pulse generator, which can change not only the frequency of output pulse but also the duty of output pulses, by storing a reference oscillator circuit, a counter group, a program circuit, etc., in one case and controlling them by the external output. CONSTITUTION:The oscillated output from crystal vibrator 9 where an inverter is connected in series is applied to frequency dividing counter circuis 18 and 19 through waveform shaping buffer inverter 17. Next, this output is applied to frequency dividing counter circuits 20 to 24 through a gate, and the output of these circuits is sent to output terminal 27 through output buffer 26. Here, program frequency dividing control circuit 25 is beforehand connected to each counter circuit and the gate, and a desired counter circuit of counter circuits 20 to 24 is operated synchronously with program input read syncyronizing signal 28 connected to buffer 26. Thus, the frequency and the duty of output pulses are changed to a prescribed value.
