摘要
介绍采用相关分析法测量2个同周期正弦信号相位的数字化方法。由于采用权相关分析并对串行采集误差进行了校正，使得该方法不仅精度高、速度快，而且适用于普通的串行采集方式，硬件成本较低。
This paper introduces a digital method for measuring the phase difference of two sinusoidal signals with same frequency. Correlation analytical method is used and improved, and the error of serial data sampling is corrected. This method not only has high precision, but also fits for general serial data sampling, and the cost of hardware is very low.
