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). This terminology will WebFFT算法首先由Cooly-Tuky提出了基－2FFT算法，它对 DFT的发展起到了极大推进作用。 随后又出现了混合基 算法。 本节仅对基－2FFT算法作介绍，内容包括：FFT的基本 思想、时域与频域抽取的基－2FFT算法及其程序实现。
