在Radix-2 DIT FFT算法中,N点FFT由\log_2 N个阶段组成,每个阶段由N/2点的Radix-2 DIT蝶形结构组成。每个蝶形结构运算需要1次复数乘法和2次复数加法。因此,Radix-2 DIT FFT计算总共需要的复数乘法数量为N/2\log_2N,复数加法的数量为N\log_2 N。如果剔除掉旋转因子W_N^0这种乘法,那所需的乘法次数会更...

Such an FFT algorithm can also be used for non-power-of-2 samples, but the result will be less efficient. For example, one of the common methods of calculating an FFT on a 3000-point vector is simply to pad it to 4096 with 1096 zeros and then calculate the FFT on the resulting ...
