WebSo, we can say FFT is nothing but computation of discrete Fourier transform in an algorithmic format, where the computational part will be reduced. The main advantage of having FFT is that through it, we can design the FIR filters. Mathematically, the FFT can be written as follows; x [ K] = ∑ n = 0 N − 1 x [ n] W N n k WebReal FFT is a block processing module which computes the FFT of real signals.It is for reduced memory and Mips.
