10 mai 2017 · Implementation of FFT requires the computation of butterfly unit at first, which takes two complex inputs 'a' and 'b' and a twiddle factor 'W' It generates two complex outputs 'Z1' and 'Z2' Input 'b' is multiplied with 'W' and then added to 'a' for the output 'Z1'
Fast Fourier Transform (FFT) is one of the most powerful tools in digital signal processing applications and it is also the basic transformation employed by the latest
Moreover, the computation can be implemented most efficiently using a class of algorithms, called Fast Fourier Transform (FFT) algorithms The FFT refers to a
