Complete MATLAB Implementation of FIR/IIR Low-pass and Band-pass Filters with Graphical Comparisons

This comprehensive MATLAB program developed through extensive research features fully functional implementations of FIR (Finite Impulse Response) and IIR (Infinite Impulse Response) filters, including both low-pass and band-pass configurations. The code demonstrates practical filter design using MATLAB's signal processing toolbox, with side-by-side graphical comparisons of pre-filtered and post-filtered signals to visualize frequency response characteristics and filtering effectiveness.
