Design of Analog Signal Modulation System Based on MATLAB/GUI

摘要: 本文设计了一个基于MATLAB/GUI的模拟信号调制系统，用于教学和技术开发的仿真应用。该系统包括用户登录、调制类型选择、参数设置、绘图、计算和结果输出六大功能模块。用户可以通过交互式和可视化的界面灵活更改参数，并实时展示对应结果，同时支持参数与结果导出实现数据可追溯。本文还介绍了AM和FM调制的原理与计算公式，以及MATLAB/GUI的基本概念和应用。该系统的设计可以有效辅助教学和技术开发，并在数据可视化方面有一定的借鉴意义。

Abstract: In this paper, a simulation signal modulation system based on MATLAB/GUI is designed as a simu-lation application for teaching and technical development. The system consists of six functional modules: user login, modulation type selection, parameter setting, plotting, calculation, and result output. Users can flexibly change parameters through an interactive and visual interface, and cor-responding results are displayed in real-time. The system also supports parameter and result ex-port for data traceability. The principles and calculation formulas of AM and FM modulation, as well as the basic concepts and applications of MATLAB/GUI, are introduced in this paper. The design of this system can effectively assist in teaching and technical development, and has certain reference significance in data visualization.
