Description: FFT算法的基本原理是把长序列的DFT逐次分解为较短序列的DFT。按照抽取方式的不同可分为DIT-FFT（按时间抽取）和DIF-FFT（按频率抽取）算法。按照蝶形运算的构成不同可分为基2、基4、基8以及任意因子（2n,n为大于1的整数），基2、基4算法较为常用。-FFT algorithm is the basic principle of DFT successive long sequence is broken down into shorter sequences of DFT. In accordance with the different extraction methods can be divided into the DIT-FFT (time taken) and the DIF-FFT (according to the frequency of extraction) algorithm. In accordance with the composition of different butterfly operations can be divided into base 2, base 4, base 8, as well as arbitrary factor (2n, n is an integer greater than 1), radix-2, Radix-4 algorithm is more commonly used.

Description: 进行FFT变换。任何连续测量的时序或信号，都可以表示为不同频率的正弦波信号的无限叠加。而根据该原理创立的傅立叶变换算法利用直接测量到的原始信号，以累加方式来计算该信号中不同正弦波信号的频率、振幅和相位。当然这是从数学的角度去看傅立叶变换。(Any continuous time sequence or signal can be expressed as an infinite superposition of sinusoidal signals of different frequencies. The Fu Liye transform algorithm based on the principle is used to calculate the frequency, amplitude and phase of different sine wave signals by accumulating the original signals directly. Of course, this is the Fu Liye transformation from a mathematical point of view.)
