基于MATLAB的信号与系统实验仿真系统设计

［摘 要］本文概述了信号仿真系统的需求、总体结构、基本功能。重点介绍了利 用MatIab软件设计实现信号仿真系统的基本原理及功能，以及利用Matlab软件提 供的图形用户界而

(GraPhiCalUSerlnterfaCeS ,GUI)设计具有人机交互、界而友 好的用户界面。本文采用Matlab

的图形用户界面设计功能，开发出了各个实验界 而。在该实验软件中，集成了信号处理中的多个实验，应用效果良好。本系统是一 种演示型软件，用可视化的仿真工具，以图形和动态仿真的方式演示部分基本信号 的传输波形和变换，使学习人员直观、感性地了解和裳握信号与系统的基本知识。
