WebFast Fourier Transform(FFT) • The Fast Fourier Transform does not refer to a new or different type of Fourier transform. It refers to a very efficient algorithm for computingtheDFT • The time taken to evaluate a DFT on a computer depends principally on the number of multiplications involved. DFT needs N2 multiplications.FFT onlyneeds Nlog 2 (N)
