Web23 jun. 2024 · That makes no sense. You know that x = ifft(fft(x)). If you cut the intermediate array in half of course you won’t get x back. You also need to remove all the normalization and stuff. Just FFT, multiply by the transfer function, and IFFT. Do note that the origin is in the first element, which is important when you define your transfer function. Web16.

Web1 mei 2024 · I also used fftshift on the result of the IFFT, because the same thing applies to the time axis, it shifts the origin from the first sample to the middle of the sequence. Note how noisy f_recon is. This is explained by the poor estimates of f_k we could make with the non-uniformed sampled signal. rocky mountain smiles loveland co reviews
