WebApr 21, 2024 · 1. fftshift only changes the order of the input "samples" or "coefficients". If applied on real data, the output is real. It is meant to be applied on some fft result, not on the analysed time signal. Standard fft outputs do not emphasize on the natural symmetry around the 0 index frequency, which fftshift corrects. WebApr 5, 2016 · 12. I see this is an old thread, but for what it's worth, here's a free (MIT License) 1-D power-of-2-length-only C# FFT implementation I wrote in 2010.
