摘　　要：工频信号相位差测量技术目前已经很成熟,但是,用传统测量方法对音频或更高频率信号相位差进行高精度测量还有一定困难。文章提出了正交双通道算法实现无理论误差的信号相位差测量。The measure technology of phase difference at 50Hz sin signal is alread y very ripe.But,the traditional measure method is still powerless to carrying on high-accuracy measurement of audio frequency or higher frequency sin signal pha se difference.In the article,the two passways of perpendicular algorithm of phas e difference measurement without theory error is introduced.

关 键 词：相位差 正交双通道 数字信号处理
