Problems solved by technology

[0003] Although there are many pulse generator controls in the prior art, most of them have the problem that the width and period of the output pulse cannot be adjusted both ways. Therefore, it is necessary to provide a pulse generator to realize both the pulse width and the pulse period. adjustable

Abstract

The invention discloses a pulse signal generator, comprising a clock generation unit which is set to generate a count control signal of a set period; a count circuit which is set to trigger count through an edge of the count control signal and output a count value signal expressing a count value; a pulse width control circuit which is set to output a corresponding pulse width control signal according to input pulse width control quantity; a period control circuit which is set to output a corresponding period control signal according to the input period control quantity; a first comparison circuit which is set to compare the count value signal and the pulse width control signal and outputs a first comparison signal; a second comparison circuit which is set to compare the count value signaland the period value signal to obtain a second comparison signal; a flip-flop circuit which is set to generate a pulse signal according to the first comparison signal and the second comparison signal;and a clear circuit which is set to output a clear signal to the count circuit in a pulse period.

Description

technical field [0001] The present invention relates to the field of electronic technology, and more specifically, to a pulse signal generator. Background technique [0002] Signal generators are systems used to generate signals. Signal generators are divided into four categories according to the waveforms of the generated signals: 1) Sine signal generators, which are mainly used to measure the frequency characteristics, nonlinear distortion, and gain of circuits and systems. And sensitivity, etc., can be further subdivided into low-frequency (20 Hz to 10 MHz) signal generators, high-frequency (100 kHz to 300 MHz) signal generators, microwave signal generators, frequency sweep and program-controlled signals according to performance and use generator, frequency synthesizer signal generator, etc. 2) Function (waveform) signal generator, which can generate certain periodic time function waveforms (sine wave, square wave, triangle wave, sawtooth wave and pulse wave, etc.) signa...
