摘　　要：介绍了一种高分辨率宽频域方波脉冲的产生方法。用此方法设计的方波脉冲发生器使用方便．灵活。它不用变档即可实现高低不同频域方波脉冲的控制，且具有较高的分辨率，可实用于具有特殊要求的步进电动机驱动控制系统中。This paper introduces a method to generate square wave of high resolving power and wide frequency range. The square wave generator designed by using thismethod is nexible and convenient. It can realize the controlof square wave in high or lowfrequency wave withoutchanging the scale. And it has higher resolving power. Itmay be practically used in the stepper motor driving control system which has special demands.
