High Performance FIR and IIR Filters Based on
FPGA for 16 Hz Signal Processing
Abstract:
The goal of the research to design and implement digital filters (Finite Impulse Response (FIR) and Infinite Impulse Response (IIR)) based on Field Programmable Gate Array (FPGA) by using the copulation between MATLAB/Simulink and Xilinx ISE Design Suite programs. low pass digital filter was implemented with different types of windowing methods that calculate the filter coefficient of FIR filter and different types of IIR filter with three numbers of filter order that are (5th order, 8th order, and 10th order). These different types of digital filters and filter orders are applied with the addition of a sine signal with a frequency of 16 Hz and a random noise signal. The work was done by two approaches: the first by simulation method through coupling between MATLAB/Simulink and Xilinx ISE Design Suite programs. While the second is by the practical method of loading these simulation block diagrams on FPGA. The performance of the work is measured by the difference between the sine signal and filtered signal and by the difference between the simulation results and practical results. Using FPGA with digital filters in this research gives a major advantage which is the simulation results equal to the practical results (Difference equal to zero).
