用FFT分别计算Xa(n) (p=8, q=2)与Xb(n) (a =0.1,f =0.0625)的16点循环卷积和线性卷积。

用VHDL语言实现的16点FFT编程 非常有用的东西

FFT and IFFT for 16-bits wave, you can use this instead of convolution calculate, input samples must be 2^n. If its not 2^n samples just stuff zero in last array. I already make it to C++ class you can new a calss and do it easy

include FFT IFFT and using FFT to calculate convolution and round off. Its useful for wave 16 bits.
