1024点fft程序，在ccs上可以直接仿真，无需调试-1,024 points fft procedures, the ccs can direct simulation, debugging without

fft的c语言实现,本程序用c语言基于fft的实现方法可以实现1024长度的序列fft变换-fft of c language, c language using the program fft-based method can achieve the realization of the sequence length 1024 fft transform

用C生成1024点FFT输入的复数数据，并存在一个TXT文件中-1024-point FFT in C to generate complex input data, and there is a TXT file

FFT使用范例。 x=0.5*sin(2*pi*15*t)+2*sin(2*pi*40*t)。采样频率fs=100Hz，分别绘制N=128、1024点幅频图。-FFT usage examples. x = 0.5* sin (2* pi* 15* t)+2* sin (2* pi* 40* t). Sampling frequency fs = 100Hz, were drawn N = 128,1024 point amplitude-frequency diagram.
