本项目基于等精度测量频率的原理,利用Verilog硬件描述语言设计实现了频率计内部功能模块,对传统的等精度测量方法进行了改进,增加了测量脉冲宽度的功能 采用STC89C52单片机进行数据运算处理,利用液晶显示器对测量的频率、占空比进行实时显示。充分发挥FPGA(现场可编程门阵列)的高速数据采集能力和单片机的高效计算与控制能力,使两者有机地结合起来。-The project is based on the principle of equal precision frequency measurement, using Verilog hardware descr iption language design and implementation of the frequency meter internal function modules, such as the traditional measurement accuracy was improved by increasing the pulse width measurement function use STC89C52 MCU data processing operations the use of liquid crystal display on the measurement of the frequency, duty cycle displayed in real time. Full FPGA (field programmable gate array), high-speed data acquisition capabilities and high-performance computing and microcomputer control to organically combine the two.
