Scipy fft phase
WebFFT (Fast Fourier Transform) refers to a way the discrete Fourier Transform (DFT) can be calculated efficiently, by using symmetries in the calculated terms. The symmetry is … Web1 It's sometimes easier to understand phase if you do an fftshift of the data before applying an FFT, which references phase to the center of your sample vector. Or you can set t=0 in your generator to the center instead. The ends can be discontinuous for a non-periodic-in-aperture sinusoid, and the phase of a discontinuity can seem non-intuitive.

If we look at the phase value at the same index …
An FFT measures circular phase, referenced to both the very beginning and very end of the input data window. If your input sine wave isn't exactly integer periodic in the FFT aperture, then there will be a discontinuity between the phase at the beginning and end of the window, thus the FFT phase measurement won't be what you might expect.
