电子示波器对两个同频正弦信号相位差的两种测量方法的对比分析

A Electronic Oscilloscope for Two-phase Sinusoidal Signal with Frequency Comparative Analysis of Two Measurement Methods to

对于同频率的两正弦信号,它们的相位差就是初相之差,而初相是正弦信号的三要素之一。对正弦信号的相量表示法及对应的相关运算都与初相有关,所以相位差的测量就显得很重要了。通常对相位差的测量方法有线性扫描法和李沙育图形法。

For two sinusoidal signals with frequency,their phase difference is the difference between the initial phase,while the initial phase is positive String signals,one of the three elements.Phasor of the sinusoidal signal representation and the corresponding operations with the initial phase associated with Off,so measurement of phase difference becomes very important.Usually a linear measurement of phase difference are Linear Scanning and Linear method and Lissajous Figures law.
