Fast Fourier Transform

Fast Fourier Transform(FFT)

         Discrete Fourier Transform is considered as a computationally slow method. So, the best way to reduce addition and multiplication is using Fast Fourier Transform. Speed matters when implementation of this method comes into picture.
         This session involves taking two cases- 4 point input and 8 point input.In both these cases we execute the code for FFT and study its implementation. This execution enable us to prove its computational advantage.
