Difference between phase and frequency
WebThe frequency-domain representation of a signal carries information about the signal's magnitude and phase at each frequency. This is why the output of the FFT computation is complex. ... y1, are practically the same (the norm of their difference is on the order of 1e-14). The very small difference between the two is also due to the numerical ... WebThis difference is the phase difference: Δ ϕ = ϕ 1 − ϕ 2. Here is an example of how to calculate the wave phase and the wave phase difference. A wave with a maximum amplitude A of 2 metres is represented by a sine function. Calculate the wave phase when the wave has an amplitude of y = 1. Using the y = A ⋅ sin ( x) relationship and ...
