Description: DIT-FFT算法子程序
FFT长度为2m，m为正整数。FFT输出结果放在输入复数数组中。其中xr存放信号序列实部，xi存放信号序列虚部。如果信号长度小于N，需要给xr和xi后面补足0，计算结果x(k)的实部和虚部仍然分别存放在数组xr和xi中。-DIT- FFT subroutine FFT length of 2m, m is a positive integer. FFT output on the importation of complex array. Xr which kept real signal sequence, the signal sequence xi kept the imaginary part. If the signal is less than the length of N, and the need to xr xi behind complement 0, The results of x (k) the real and imaginary parts were still stored in the array xr and xi China.

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.
