WebApr 28, 2024 · Learn how you can do Fast Fourier Transform (FFT) in MATLAB. It starts with generating a synthesized signal and then using the FFT function to convert the si... WebFFT is a complex-valued linear transformation from the time domain to the frequency domain. For example, if you construct a vector as the sum of two sinusoids and transform it with the FFT, you can see the peaks of the frequencies in the FFT magnitude plot.
