基于GUI的数字信号处理课程演示系统研究

Matlab中的Guide是专用于图形用户界面的快速开发环境,利用该工具编程开发的数字信号处理课程演示系统,完成了用户登录界面、系统选择主界面和两个内容子模块界面的设计和编程。其中,在两个内容子模块中开发了常用典型序列的产生、基本运算、离散线性时不变系统、时域离散傅里叶变换、离散傅里叶级数、离散傅里叶变换、DFT和FFT的应用、滤波器的设计和语音信号处理等Matlab辅助分析与设计实验,该系统直观且形象,界面美观大方。

Study of the Demonstration System of the "Digital Signal Processing" Course Based on GUI

The GUIDE of Matlab is a quick development environment specially used in the graphical user interface.In the demonstration system for the course Digital Signal Processing developed by this tool,the user login interface,the main interface selected by the system,and two sub-module interfaces are designed and programmed.For the two content sub-modules some Matlab aided analysis and design of experiments such as typical sequence generation,basic operations,discrete linear time invariant systems,time domain Discrete Fourier Transform(DTFT),Discrete Fourier Series(DFS),DFT,applications of the DFT and FFT,filter design and speech signal processing are developed.The system interface is friendly and open,which is beneficial for students to comprehend the DSP theory and greatly improve the teaching effect and efficiency.
