Hi all! I hope this is the right subcategory to ask in. I’m playing around with the FFTW package to perform some Fourier transforms. I got how to define a signal and transform it, but I can’t get how (and why) can I shift the frequency domain to reflect the actual frequencies of my signal. My Googl…

How do frequencies shift after a FFT?
