摘要
介绍一种基于双积分原理的精密相位测量电路。该电路可测量两个同频率正弦波之间的相位差,并能显示超前或滞后。文中给出了电路原理图,并详述其工作原理及特点。
In this paper, a precision phase measurement circuit based on double integration method was introduced. The circuit can measure the phase difference between two sine waves of equal frequency, and show the lead or lagging. The basic circuit diagram was shown, and its principle and feature of circuit were described in detail.
