GUI-Based Filter Design Interface

By utilizing MATLAB's Graphical User Interface (GUI) design environment, you can efficiently design IIR (Infinite Impulse Response) filters for signal processing applications. This interface enables precise extraction of target signal components through customizable filter configurations. The GUI implementation leverages MATLAB's built-in filter design functions (such as butter, cheby1, ellip) and provides interactive controls for selecting filter types (Butterworth, Chebyshev, etc.), setting critical parameters (passband/stopband frequencies, ripple factors, filter order), and visualizing frequency responses through magnitude/phase plots. The object-oriented approach allows dynamic updates of filter characteristics using callback functions when modifying design parameters. This intuitive workflow supports customized filter design tailored to specific signal processing requirements in applications ranging from audio processing and image enhancement to biomedical signal analysis. The interface combines theoretical filter design algorithms with practical implementation tools, making it an essential resource for both educational and professional signal processing projects.
