摘要
本文给出一种测量低频频率特别是工频电压信号频率及相位的新方法。该方法仅需对两个输入信号进行同时采样，获得每一正弦信号的五个采样点，即可根据本文提供的公式计算出信号的频率与相似。
A new method for measuring frequency and phase difference between two si- nusoids is presented in this paper. Two Sampled five point values of the input signal are gotten by means of synchronous Sampling method , the frequency and phase difference will be obtained through the formula that has been presented. This method can realize the measurement of fre- quency and phase difference realtimely .
