Notes 3, Computer Graphics 2, 15-463 Fourier Transforms and the Fast Fourier Transform (FFT) Algorithm Paul Heckbert Feb. 1995 Revised 27 Jan. 1998 Fourier transform is a mathematical operation which converts a time domain signal into a frequency domain signal. This fact is the central philosophy behind Fourier transforms (Fourier was very French, so his name is pronounced a little wonky: “4 E yay”). A complicated signal can be broken down into simple waves. This break down, and how much of each wave is needed, is the Fourier Transform.
