However, the same computation can be done with only N Log2N complex multiplications, when a radix-2 (N is a power of 2) FFT is used. This is especially significant for large values of N: when N = 128, the number of complex multiplications is 16384 for direct computation of DFT and only 896 for a radix-2 FFT computation. • FFT algorithms also exist when N is not a power of 2. These algorithms are called non-radix-2 FFT. Practical Usage of the FFT: Computation of Fast Fourier Transform with MATLAB The FFT was a major breakthrough in the efficient and fast computation of the Fourier transform of speech, music, and other fundamental signals.
