高速高精度频率测量系统的CPLD实现

The Realizing of High-speed and High-accuracy Frequency Surveying Systbm in CPLD

介绍了等精度测频原理,分析了测量误差。在一片CPLD上实现频率测量和数据处理,设计了宽范围、高集成度、高速、高精度和高可靠性的频率测量系统。

In this article, the theory of the same accuracy frequency measurement is introduced, surveying error is analysed. The frequency measurement and data processing is realized in a chip CPLD. The frequency surveying system of wide range and high integrated and high speed and high accuracy and high reliable is designed.
