【摘要】 若两路正(余)弦被测信号含有加性噪声,要准确测量其相位差必须要采取一定措施消除噪声的影响。用正交双通道处理技术对此两信号进行互相关函数处理,可以检测出被噪声淹没的正(余)弦信号的相位差。更多还原

【Abstract】 If two sine(cosine) signals to be measured contain additive noise,certain measures must be adopted in eliminating noise influences to correctly measure their phase differences,and the submerged phase difference of sine(cosine) signals could be measured by using orthogonal two-channel processing technology to process the two signals.更多还原
