基于CPLD的动态频率信号测量装置的设计与实现

Design and Implementation of Dynamic-Frequency Measurement Device Based on CPLD

提出了一种基于单周期测频原理的动态频率信号测量方法,给出了动态频率信号测量装置的设计方案及其具体实现。该装置能够很好地跟踪频率信号的动态变化,且工作稳定可靠;同时还具有体积小、功耗低、便于携带等优点。

This paper presents a new dynamic-frequency measurement method based on single-period frequency measuring principle and proposes the design and implementation of a measurement device using this method. The device can track the dynamic changment of frequency very well, and work with high-reliability. In addition, the device has features of miniature-volume, low-comsumption, and easy-portability.
