数字式相位差调制器及测量器

A Digital Phase Differential Modulator and Measurer

介绍了相位差调制器及测量器的原理框图、主要性能指标及电路实现。前者利用数控脉宽调制方法对两路输出的同频脉冲信号进行相位差调制；后者采用锁相技术，实现对同频脉冲信号相位差的精确测量。

In this article, the schematic diagram, main specifications and the realization of the circuits of the phase differential modulator and measurer are described. The modulator, based on the digital controlled PWM technique, realizes the phase differential modulation of two channel output of identical frequency pulse signals; The measurer, based on the phase lock technique, realizes the precise measurement of the phase differential of identical frequency pulse signals.
