Phase Difference between two Signals - MathWorks

WebIn practice, if the phase difference is reasonably small (say 90 degrees or less), you could call the one with the larger phase "leading" because the peaks are relatively close together and the one with the larger phase visually appears to come first. However with larger phase differences and especially 180 degrees that makes no sense any more. Web23 jan. 2024 · Use the frequency and period of the wave. Then the equation is: Phase shift = 360 * time / wave period Phase shift is in degrees and time is the time difference. And you don’t want to find the angle of each signal rather you want to find the phase angle difference between the two sine waves. Share Cite Follow edited Jan 23, 2024 at 12:17 takes two to talk
