Butterworth Notch Filter Program

This document presents a fully functional Butterworth notch filter implementation designed for direct execution in MATLAB. The program utilizes Butterworth filter design principles to create notch filters that selectively attenuate specific frequency bands while preserving other frequency components. Key implementation details include: - Uses MATLAB's signal processing functions for filter design and implementation - Implements Butterworth filter coefficients calculation for precise frequency rejection - Includes proper frequency response plotting and filter testing routines Important note: To ensure successful execution, users must verify that their MATLAB working directory matches the directory structure expected by the program. This includes checking path configurations and file locations to avoid runtime errors related to missing dependencies or incorrect file paths. The program is structured to provide immediate functionality upon proper setup, allowing users to quickly apply notch filtering to their signal processing applications without additional modifications.
