FIR filters using on-board ADC-DAC & FPGA

Electronics industry is very prodigiously moving towards digital platform, but the world is analog in nature, so when any analog signal needs to be processed in digital platform it should be converted to digital with the help of analog to digital converter. After processing through digital platform by the help of DAC it will be again converted to analog format. Here the digital platform is ALTERA CYCLONE-II FPGA. FIR filters are used in every aspect of present-day technology because filtering is one of the basic tools of information acquisition and manipulation. Different types of digital FIR filters are implemented on external signal by using VERILOG HDL language over FPGA. Further model based design approach using MATLAB and Simulink is taken into account for optimized designing and resource computation.
