数字信号处理教学演示系统设计

Teaching Demonstration System Design for the Course of Digital Signal Processing

“数字信号处理”课程是一门理论性较强的专业基础课,针对学生在学习此课程的过程中存在对抽象知识点难以理解等问题,基于Matlab GUI仿真平台设计了一款数字信号处理教学演示系统。该系统涵盖了运算、卷积、傅里叶变换、信号采样与重构、数字滤波器设计等经典算法以及语音信号处理综合案例。在教学演示过程中,该系统可灵活地进行参数调整,并可生成可执行文件,方便教学应用演示,同时有利于师生互动,帮助学生加深对重点、难点知识的理解,提高课堂效率。

The digital signal processing is a basic theoretical professional course,where some abstract points are difficult to understand for the students.Aiming at this problem,a digital signal processing teaching demonstration system is designed based on Matlab GUI simulation platform,which covers classical algorithms such as calculation,convolution,Fourier transform,signal sampling and reconstruction,digital filter design etc.,and comprehensive cases of speech signal processing.In the process of teaching demonstration,this system can flexibly adjust parameters and generate executable files to facilitate the teaching.Additionally,it is conducive to teacher-student interaction and to help students better understand the key and difficult points,so as to improve the classroom efficiency.
