数字频率计在数字化测量中具有十分重要的地位和作用,在当今的科学技术研究中,实现某些量的数字化测量,对问题的分析处理是非常方便的.实现模拟量的数字化测量是电子学的一个重要组成部分。这种 CMOS数字频率计除可以作为一般频率计使用外,电路稍加改进还可测量周期等一些与时间有关的物理量,与其它仪器配套使用,作为计数显示单元,可以实现某些量的数字化测量。本文对电路设计与制作过程作一简略 Digital frequency meter in the digital measurement has a very important position and role in today’s science and technology research to achieve some amount of digital measurement of the problem analysis and processing is very convenient to achieve analog digital measurement of electronics An important part of. This CMOS digital frequency meter except can be used as a general frequency meter, the circuit is slightly improved can also measure the cycle and some other time-related physical quantities, and supporting the use of other instruments as a counter display unit, you can achieve some of the amount of digital measurement . This article on the circuit design and production process to make a brief
