Digital Signal processing ranks among the most demanding applications of digital design concepts and practices. In general, it has a rich history, and its importance is evident in diverse fields as biomedical engineering, acoustics, Sonar. The importance of the digital signal processing appears to be increasing with no visible sign of saturation. It is a mature technology domain wherein the demands for enhanced performance and reduced resource utilization have risen exponentially over the years.Digital Signal Processing (DSP) deals with the manipulation of digital signals using complex signal processing systems built from basic building blocks like filters and signal transformations.The advent of engineering tools like MATLAB has enabled the design of these basic building blocks faster and more accurate. Recent advancements in Field Programmable Gate Array (FPGA) design technology, has resulted in FPGA(s) becoming the preferred platform for evaluating and implementing signal processing algorithms. Special features of the FPGA architecture, like embedded multipliers, fast carry chains, scalability and re-configurability make it a very attractive platform for complex signal processing algorithms.This document provides a brief discourse to design, to check the feasibility of filter and implementation of digital filter algorthims based on field programmable gate arrays FPGAs).
