[PDF] Fourier Transforms and the Fast Fourier Transform (FFT) Algorithm
The FFT is a fast algorithm for computing the DFT If we take the 2-point DFT and 4-point DFT and generalize them to 8-point, 16-point, , 2r-point, we get the FFT algorithm The FFT algorithm computes the DFT using O(N log N) multiplies and adds There are many variants of the FFT algorithm
