WebThe fast Fourier transform (FFT) is an algorithm for computing the discrete Fourier transform (DFT), whereas the DFT is the transform itself. Another distinction that you’ll see made in the scipy.fft library is between different types of input. fft () accepts complex-valued input, and rfft () accepts real-valued input. WebJun 26, 2024 · The fft is at heart an operation using complex variables. You can use sines and cosines, multiply amplitudes by 2, except don't multiply X (1) by 2, all that kind of stuff. Some of that is good for plotting purposes. But if you want to get back to the time domain it's far easier to use complex amplitudes and exp ( i* ...). circus circus las vegas checkout
