摘　　要：本文提出一种测量低频率范围内两正弦信号之间相位角θ的新方法。这种方法利用同步取样技术获得两输入信号的取样序列,经过对瞬间幅值的处理和迭代校正得到被测相位角θ。它具有使用硬件少,计算简便的特点,文章还对测量误差进行了分析,并给出了模拟仿真结果。A new method for measuring phase difference between two sinusoids with the lower range of frequency—Sampling Numerical method, is described in this paper. Originally, two sampled sequences of the input sigal are gotten by means of synchronous sampling technique and its transient amplitudes are preprocessed. So the phase difference will be obtained through the use of iterative and correcting techniques. This method have the advantages of less hardware and computation. Moreover, the analysis of measuring error and simulating results are also given in this paper .
