Text: One-Dimensional FFTs 6 6.5 RADIX-4 FAST FOURIER TRANSFORMS Whereas a radix-2 FFT divides an N-point sequence successively in half until only two-point DFTs remain, a radix-4 FFT divides an N-point , radix-4 FFT , just as the two-point DFT is the butterfly for a radix-2 FFT . A radix-4 FFT essentially combines two stages of a radix-2 FFT into one, so that half as many stages are required. The radix , the number of butterflies in a radix2 FFT .
