基于等精度测频工作的相位测量仪设计

The Design of Phase Measure Based on the Equal Precision Frequency

本文阐述了等精度频率测量的原理,介绍了利用其高精度的特点来测量信号的频率,在此基础上实现了测量不同相位的两路信号之间的相位差,并给出了具体的逻辑电路设计方法及VHDL语言的层次设计方法。

This paper expound the principle about the equal precision frequency measure, and introduce how to measure the signal frequency by the high precision characteristic. Then the paper implement the phase measure between the two different phase but same frequency signal, give the detailed logic circuit design way and the arrangement design based on the VHDL language.
