FFT

We performed Fast fourier transform in 3rd experiment . In FFT,The procedure of  performing the butterfly computations and returning the result to memory is repeated many times .this repetition takes place ( (N log2 (N))/2 times ) in the computation of an N-point DFT. For DSP processor radix 2 or 4 decimation in frequency, FFT algorithm are preferable in terms of speed and accuracy.

    Obvious calculations are avoided by these algorithms avoiding unnecessary memory space for storage. That's why it is fast.
