WebRadix-4 FFT Algorithm. When the number of data points N in the DFT is a power of 4 (i.e., N = 4 v), we can, of course, always use a radix-2 algorithm for the computation. However, for this case, it is more efficient computationally to employ a radix-r FFT algorithm. Let us begin by describing a radix-4 decimation-in-time FFT algorithm briefly. WebRADIX-2 FFT The radix-2 FFT algorithms are used for data vectors of lengths N = 2K. They proceed by dividing the DFT into two DFTs of length N=2 each, and iterating. There are several types of radix-2 FFT algorithms, the most common being the decimation-in-time (DIT) and the decimation-in-frequency (DIF).
