Signal Analysis Application Developed with MATLAB GUI

This MATLAB GUI-based signal analysis application serves as an educational tool for mastering GUI development techniques. The program demonstrates practical implementations of signal processing algorithms including time-domain analysis (using functions like plot and stem for waveform visualization), frequency-domain analysis (employing FFT algorithms via fft function), and filter design (utilizing filter design toolbox functions like butter and fir1). Users can explore core signal processing concepts through interactive controls and real-time parameter adjustments. The application provides comprehensive documentation and commented source code examples, featuring GUI component callbacks and data flow management through handles structure. Both novice and experienced users can benefit from hands-on experimentation with signal generation, spectral analysis, and digital filter implementation using GUI sliders, buttons, and axes components for interactive learning.
