This MATLAB-based utility provides efficient signal envelope extraction capabilities. The application employs Hilbert transform algorithms for accurate envelope detection, incorporating preprocessing filters to enhance signal quality before envelope calculation. It features an intuitive GUI interface with interactive signal visualization tools, allowing users to view original signals alongside extracted envelopes. Key functionalities include signal preprocessing (filtering and normalization), envelope extraction using analytic signal computation, and real-time data visualization with zoom/pan controls. The code implements efficient frame-based processing suitable for both stationary and non-stationary signals, with customizable parameters for envelope smoothing and peak detection thresholds. Suitable for research, engineering applications, and educational purposes, this tool offers a comprehensive solution for signal analysis tasks across various domains.
