MATLAB Virtual Signal Generator with Customizable Waveforms and White Noise

This MATLAB source code implements a virtual signal generator capable of producing custom waveforms and white noise. The generator features a user-friendly interface for easily configuring signal parameters such as frequency, amplitude, and duration through GUI input controls. It supports multiple waveform types including sine waves (using sin() function), square waves (via square() function), triangular waves (using sawtooth() function), and more, allowing users to select waveforms through dropdown menus or parameter inputs. The implementation includes white noise generation using MATLAB's randn() function for Gaussian distribution, with adjustable noise levels controlled through amplitude scaling parameters. The core algorithm handles signal synthesis through mathematical waveform generation functions combined with noise addition operations, ensuring precise control over signal characteristics. This versatile tool facilitates various signal processing experiments and research applications, providing a flexible solution for waveform generation needs.
