Title: A FIR filter with variable order based on FPGA
Abstract: Considering the low accuracy of the fixed-point FIR filter and the disadvantages of fixed filter order, a design to realize a FIR filter using floating-point with variable order based on FPGA was introduced. This kind of FIR filter realizes the function of changing orders without additional hardware resources. Using the simulation tool of Vivado and MATLAB, the relative error of the FIR filter is less than 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-3</sup> , which indicates that this kind of FIR filter enjoys high accuracy.
