摘要
介绍一种基于单片机的宽带高精度变闸门频率测试法,并给出该方法的测试原理及软、硬件组成。本设计以AT89C51单片机为测频的核心器件,用单片机的软件控制程序取代复杂的外计数电路,从而达到简化电路,提高测量精度的目的。总体看来,该设计具有结构简单,功能齐全,使用方便的特点。
A new method of frequency measurement is presented in this paper. The measurement principle and the configuration of software and hardware for the instrument are also given. Using the single chip microcomputer the design makes the software control instead of the complex circuit , and makes the circuit simple and also improves accuracy.
