[Windows Develop] FastFourierTransform DL : 0: This function is written to understand and/or explain an fft algorithm and usage of radix2 procedure. This function take the signal which you want to find FFT, for m bit you can also call the function without entering a signal or number of points, because there is default values for y and m which are y = sin(2*pi*50*t)+sin(2*pi*120*t) m=3 you can see the steps of order reversing used as built-in function but non others. you will also see the taking butterfly tree steps. for more information read the help file of function. in future this can be improve as selective radix or any other feature you suggest please notice me for any sugestion.

[Mathimatics-Numerical algorithms] fft DL : 0: 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.

[DSP program] Radix-4FFTforTMS320C6000 DL : 0: 用TI DSP芯片TMS320C6000实现FFT算法内含程序代码和说明 The radix-4 FFT-Fixed-point digital signal processors (DSPs) have limited dynamic range to deal with digital data. This application report proposes a scheme to test and scale the result output from each Fast Fourier Transform (FFT) stage in order to fix the accumulation overflow. The radix-4 FFT algorithm is selected since it provides fewer stages than radix-2 algorithm. Thus, the scaling operations are minimized. This application report is organized as follows:

[Embeded-SCM Develop] fft-arm DL : 0: 一个用于ARM的基4/基5定点FFT算法，原作者是JDB，后来我扩展过16和256点的计算并用在项目中了，感觉速度还不错。现在重写了基于Linux GCC4的测试程序，可供使用者评估参考。建议安装FFTW3用来精确评估测试结果，相关范例已经在代码中了。-Radix 4/5 FFT routines supporting 16/64/256 and 20/80 calculations. The source originally contributed by JDB, I had extended 16 and 256 candidates and used it in our project it has been verified as fast and stable. Now we add some test vectors running on Linux with GCC 4 for testers who want to use or just evaluate it. Installing FFTW3 is recommended for evaluating the code exactly.
