数字频率计是一种用来测试周期性变化信号工作频率的装置。其原理是在规定的单位时间（闸门时间）内，记录输入的脉冲的个数。我们可以通过改变记录脉冲的闸门时间来切换测频量程。本文利用EDA技术中的Max+plusⅡ作为开发工具,设计了基于FPGA的8位十进制频率计,并下载到在系统可编程实验板的EPF10K20TC144-4器件中测试实现了其功能。-Digital frequency meter is a kind of cyclical changes in the signal used to test the device operating frequency. The principle is that the specified unit of time (gate time), the record of the number of input pulses. We can change the record time to the gate pulse frequency measurement range switch. In this paper, the use of EDA technology Max+ plus Ⅱ as a development tool designed for FPGA-based 8-bit decimal frequency meter, and to download the experimental in-system programmable EPF10K20TC144-4 board test device to achieve its function.
