摘要
在对三种测频方法进行分析的基础上,介绍了基于EDA技术的等精度测频原理。给出采用AT89C51实现控制并通过FPGA来设计多功能等精度数字频率计的具体方法。该频率计可以兼顾频率计对速度、资源和测频精度等各方面的优化需求。
Analyzing the three frequency - measuring methods, the paper introduces the equal precision frequency principle based on EDA technology. The paper shows the details of achieving control on the application of AT89C51 and design of multifunctional equal precision frequency meter through FPGA. This frequency meter can also give attention to preferential requirement to speed, resources and the accuracy of frequency - measuring.
