摘 要
在电子技术中，频率是最基本的参数之一，并且与许多电参量的测量方案、测量结果都有十分密切的关系，因此频率的测量就显得更为重要。频率计可以用纯硬件电路搭制。其包括信号输入、信号放大、信号选择、时钟提供、数据显示等功能模块。为了实现智能化的计数测频，实现一个宽领域、高精度的频率计,一种有效的方法是将单片机用于频率计的设计当中。本课题介绍以51单片机作为核心器件。由于本设计采用了模块化的设计方法，提高了测量频率的范围。并且本次设计包括硬件画图和软件程序编写。 关键词：测量；频率计；单片机；汇编

Abstract
Among electronic technology, frequency is one of the most basic parameters,and result of measuring have a very close relation to a lot of electric parameters, so the measurement of frequency seems even more important. Frequency counter can take the system with pure hardware circuitry. It includes the signal input, signal amplification, signal selection, the clock provides the data display modules. In order to realize the counting of intellectualityexamines frequently, realize a wide-range, high-accuracy cymometer, an effective method is to use one-chip computer for the design of the cymometer. Thissubject recommends regarding 51 Single-Chip computer as the key device, include signal input, signalamplify, signal choose, clock offer, data person who reveal function digital design method of cymometer of module still in addition.The hardware circuit of the cymometer is drawing with Protel mapping software,the one-chip computer control procedure of the software part, wrote the assembler language. Because originally design the design method to adopt module, improve the range of measuring frequency. And the drawing of this design,including hardware and software programming
