International Journal of Emerging Science and Engineering (IJESE 5 (6): 1-10 (June 2018)

This research presents a design for both Fast Fourier Transform (FFT) and Fast Discrete wavelet transform (FDWT) by using the simplest algorithms in their respective design. Both the Haar wavelet and Decimation in Frequency implementations were performed. The performance of these two transformations was verified through their implementation using both VHDL and Xilinx System Generator (XSG) applied by MATLAB version R2012a and ISE design suite version 14.6.Finally, the difference between them is shown by comparing the speed of performance and signal processing in addition to the size of the design
