摘要

介绍了信号分析与处理课程中卷积的基本原理和定义。从建模分析到Matlab软件实现，引导学生利用卷积技术自行设计一个回波系统，使学生掌握卷积的本质、脉冲响应和系统的概念。提出了一种利用Matlab软件制作仿真回波系统的方法，以声音信号作为系统的激励和响应。通过实验，学生可以听到自己制作的系统发出的回声，增强了学生对系统概念的理解，提高了学生对课程的兴趣，对教学起到了很好的效果。

Convolution Teaching Simulation Design Based on Matlab——Echo System

Fundamental and definition of convolution in the course of Signal Analysis and Process was introduced. From modeling analysis to realization by Matlab software,students can be led to design an echo system by themself,using the convolution technology,which can make the students grasp the essential of convolution,impulse response and concept of system. One proposed a method to make a simulated echo system by Matlab software,taking sound signals as the excitation and response of the system. From the experiment,students can hear the echo sound from systems made by their own,which can enhance their understanding to the concept of system,improve their interests to the course,and take good effect on teaching.
