WebThe FFT can be thought of as producing a set vectors each with an amplitude and phase. The fft_shift operation changes the reference point for a phase angle of zero, from the edge of the FFT aperture, to the center of the original input data vector. WebThe fast Fourier transform (FFT) is a computationally efficient method of generating a Fourier transform. The main advantage of an FFT is speed, which it gets by decreasing the number of calculations needed to analyze a waveform. A disadvantage associated with the FFT is the restricted range of waveform data that can be transformed and the need ...
