Fast Fourier Transform (FFT) is one of the important signal processing algorithms because of its applications in digital filtering, communication, image processing, spectral analysis and estimation etc. Butterfly computation is the basic operation in the FFT algorithm. In this work, a novel approach is thought of and used in implementing the butterfly element. Distributed Arithmetic Algorithm (DAA) is used to do the butterfly computation instead of using conventional multipliers and adders… Expand
