Abstract
Depending on the response of the system, digital Filters can be designed using frequency sampling or windowing methods; but these methods have a problem in precise control of the critical frequencies. In the sampling method, the weighted approximation error between the actual frequency response and the desired filter response is spread across the pass-band and the stop-band and the maximum error is minimized, resulting ripples in the pass-band and the stop-band. The frequency sampling method has the same tolerance requirements as the windowing method. In this work we implemented a digital FIR high pass filter using MATLAB program (FDATools) using sampling and windowing methods, then the design in the FPGA kit is downloaded by generating VHDL description. A comparison the amount of the component has been used in the FPGA for both methods. The FIR filter is implemented using Spartan 3AN- XC3S700a-4FG484 FPGA and simulated with the help of Xilinx ISE (Integrated Software Environment) Software WEBPACK Project Navigator 11i.
