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: 这个傅立叶实例算法使用了基2、基3、基4、基5、基8、基10……混合算法，几乎可以计算任意长度的FFT。说明白点也就是当序列长度n为2、3、5、7、11等这些比较小的素数时，或者n的最大素因数<=37时，可计算这个序列的FFT。-The Fourier algorithm uses an instance of the base 2, base 3, base 4, base 5, base 8, base 10 ... ... hybrid algorithm can calculate almost any length of FFT. Say clearly that that is when the sequence length n for 2,3,5,7,11 and so on these relatively small prime numbers, or when n, the largest prime factor "= 37 hours, calculate the sequence of the FFT.
