IMPLEMENTATION AND EVALUATION OF A 10TH-ORDER LOW-PASS FINITE IMPULSE RESPONSE FILTER

Abstract

This paper presents the process of designing and analyzing a low-pass FIR (Finite Impulse Response) filter using window functions in the MATLAB environment. The theoretical foundation is discussed, including impulse response, transfer function, and stability considerations. The study is based on an experiment aimed at constructing a practically realizable version of an ideal filter, calculating its coefficients, and comparing its frequency characteristics. The results demonstrate that the resulting 10th-order filter closely approximates an ideal low-pass filter and exhibits both stability and a linear phase response.
