Virtual Signal Generator

Resource Overview

A GUI-based tool that generates (1) periodic functions (including sine, triangular, sawtooth, and square waves) with configurable amplitude, frequency, and phase parameters, (2) squared pulse sequences with adjustable amplitude, frequency, phase, and duty cycle, (3) dual-parameter exponential functions, (4) Gaussian curves with varying ranges, standard deviations, and means, and (5) Gaussian noise with different amplitudes. The implementation utilizes mathematical waveform generation algorithms with real-time parameter modulation capabilities. Users can add offsets or Gaussian noise to any of the first four functions and perform signal arithmetic operations (addition/multiplication) with predefined signals through intuitive GUI controls.

Detailed Documentation

The Virtual Signal Generator is a MATLAB-based graphical user interface tool designed for synthetic signal generation. It employs mathematical algorithms to create customizable waveforms including: periodic functions (sine, triangular, sawtooth, square) with programmable amplitude, frequency, and phase parameters; squared pulse sequences with configurable amplitude, frequency, phase, and duty cycle using pulse-width modulation techniques; dual-parameter exponential functions for decay/growth simulations; Gaussian curves with adjustable range, standard deviation, and mean values through normal distribution algorithms; and Gaussian noise generation with variable amplitude using random number generators. The system architecture allows users to apply DC offsets or superimpose Gaussian noise onto any of the primary waveforms. Advanced signal processing features include arithmetic operations (addition and multiplication) between predefined signals through matrix operations and real-time parameter adjustment via GUI sliders and input fields. The tool's modular design ensures flexible waveform combination and parameter tuning, making it suitable for educational demonstrations, signal processing testing, and electronic simulation scenarios requiring precise signal synthesis capabilities.
