Webwill explains the functioning of Radix-8 FFT Algorithm. In this Mixed Radix the length of N=32-points is recursively partitions into four parts DFTs of groups of every eighth sample. Due to the presence of eighth sample in every DFT parts for computational the DIT Radix-8 FFT is used. The outputs of these shorter 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.
