MATLAB Implementation for Electrical Signal Processing: Baseline Wander and Power Line Interference Removal

This project demonstrates electrical signal processing using MATLAB, featuring: 1) Adding 0.5Hz baseline wander and filtering with 0.5Hz high-pass filter (comparison plots and frequency response analysis) 2) Injecting 50Hz power line interference and filtering with 50Hz notch filter (waveform comparison and filter characteristic analysis). Code implementation includes signal generation, filter design using butterworth/notch functions, and comparative visualization techniques.
