Description: 最近用Mega128写了一个128点FFT程序,浮点运算,加汉宁窗。由于窗函数和旋转因子通过查表得到,所以速度还可以,程序中给的初值是通过高速AD采集的20KHz正弦信号。计算结果与Matlab的FFT函数得到的结果相同。 -Mega128 recently wrote a 128-point FFT procedures, floating-point operations, Hanning window. Since the window function and the twiddle factor look-up table has been adopted, so the speed can also be, the initial value to the process through high-speed AD collected 20KHz sinusoidal signal. The calculation results with the Matlab

Description: FFT算法实现
Radix2 可以计算 4,8,16,32, 64,128, 256....点FFT
Radix4 可以计算 4,16, 64, 256, 1024...点FFT
FFT_DIT_general.c 实现了 Radix2 和Radix4 的配合使用,可以计算Radix2可以计算的所有FFT,但效率比Radix2高。-FFT can be calculated Radix2 algorithm 4,8,16,32, 64,128, 256 .... can calculate the FFT Radix4 points 4,16, 64, 256, 1024-point FFT FFT_DIT_general.c ... Radix2 and Radix4 achieved with the use of Radix2 can calculate can calculate all the FFT, but Radix2 high efficiency.
