【摘要】在电子技术中,频率是最基本的参数之一,频率检测是电子测量领域最基本的测量之一。数字频率计时一种直接用十进制数字显示被测信号频率的测量装置,它不仅可以测量正弦波、方波和尖脉冲信号的频率,而且还能对其他物理量进行测量。数字频率计的设计有很多种方法。 【关键词】数字频率计、频率测量 【Abstract】 In electronics, the frequency is one of the most basic parameters, the field of electronic measurement frequency detection is one of the most basic measure. A direct digital frequency timing signal to be measured in decimal figures show that the frequency of the measuring device, which not only can measure the sine wave, square wave pulse signal frequency and sharp, but also for other physical measurements. The design of digital frequency meter There are many ways. 【Key words】 digital frequency meter, frequency measurement
