WebIf one draws the data-flow diagram for this pair of operations, the (x0, x1) to (y0, y1) lines cross and resemble the wings of a butterfly, hence the name (see also the illustration at right). A decimation-in-time radix-2 FFT breaks a length-NDFT into two length-N/2 DFTs followed by a combining stage consisting of many butterfly operations. WebThe FFT algorithms are broadly classified as Decimation In Time (DIT) and Decimation In Frequency (DIF) algorithms.
