WebMay 10, 2007 · This algorithm should give only a first impression of the FFT construction. The FFT (x) function is called twice recursively on the even and odd elements of the source data. After that some transformation on the data is performed. The recursion ends if the data length becomes 1. Although the abstract Cooley–Tukey factorization of the DFT, above, applies in some form to all implementations of the algorithm, much greater diversity exists in the techniques for ordering and accessing the data at each stage of the FFT. Of special interest is the problem of devising an in-place algorithm that overwrites its input with its output data using only O(1) auxiliary storage. The most well-known reordering technique involves explicit bit reversal for in-place radix-2 algor… how is bartering used today
