Design of Equiripple Linear-Phase FIR Filters Using MATLAB
Min-ge Chen · 2011
This passage briefly introduces a method of designing equiripple linear-phase FIR filters using Remez function. And the method is simulated based on MATLAB. The result of simulation satisfies the designing requirements, and this method is proved to be an optimum design method. With the same parameters, the length of filter with the method is short than them with WINDOW function method and frequency sampling method. Furthermore, it is a very simple one and easy to use.
