数字频率计作为一种常见的应用电子仪器设备,传统的一般可以完全由硬件电路搭接而成,如采用基于555 定时器电路的多功能数字频率计的设计便是可取的路径之一,不用依靠单片机。但是这种电路存在一些缺点,且测频精度也不如单片机的高。在科学研究和生产实践中,如工业过程控制,生物医学,地震模拟机械振动等领域常常要用到频率计。利用单片机采用程序设计方法来设计频率计,其测频精度高。且线路相对简单,结构紧凑,价格低廉,系统稳定度高,抗干扰能力强,用途广泛等优点-Digital frequency meter is

频率计的基本原理是用一个频率稳定度高的频率源作为基准时钟,对比测量其他信号的频率。通常情况下计算每秒内待测信号的脉冲个数,此时我们称闸门时间为1秒。闸门时间也可以大于或小于一秒。闸门时间越长,得到的频率值就越准确,但闸门时间越长则没测一次频率的间隔就越长。闸门时间越短,测的频率值刷新就越快,但测得的频率精度就受影响。本文数字频率计是用数字显示被测信号频率的仪器,被测信号可以是正弦波,方波或其它周期性变化的信号。如配以适当的传感器,可以对多种物理量进行测试,比如机械振动的频率,转速,声音的频率以及
