摘要/Abstract

摘要：

信号与系统课程的概念抽象、公式繁杂，实验教学能更好培养学生操作技能和创新能力，然而传统的实物实验存在许多不足之处，本系统利用MATLAB/GUI提供的可视化界面，设计和实现包括滤波器、连续信号的分解与合成、信号的抽样与恢复、信号的调制解调等模块的实验系统，对其功能一一进行演示，对原理结论进行验证。本系统操作简单，用户能够根据要求自行输入参数设计实验系统。系统反映直观，对比信号通过该对应系统的输出响应可促进学习者对抽象理论的快速理解，有利于创新意识和创新能力的培养。

关键词: 信号与系统, 虚拟实验, MATLAB, GUI

Abstract:

In the course of signals and systems， not only the theories are abstract， but the formula are very complex. The experimental teaching enables students to develop their skills and innovation abilities better. However, traditional experiments have many disadvantages, such as the inconvenience and immobility, that is to say their portability is poor. Besides, it is usually difficult for us to change circuit connection and circuit parameters. Based on the programming language MATLAB with GUI which can provide a visualized interface, the system including four blocks—filter, continuous periodic signals decomposition and synthesis, signal sampling and recovery, signal modulation and demodulation, are designed. In this system, the theories are explicitly presented. Using the system, users can input parameters according to their demands, the operation is just simple. As a result, the system is very helpful for users to understand the comprehensive abstract theories, and is very helpful for students to cultivate and improve their consciousness and ability of creativity.
