毕业设计－基于MATLAB的数字号处理虚拟实验仿真平.doc

摘 要 《数字信号处理》在大专院校的通信类及电子类专业中是一门非常重要的基础课程, 具有内容抽象，学生不容易掌握的特点。另一方面，教师在讲授主要些内容时也不方便。针对教学中存在的这种问题，为了方便教师授课和学生学习，使抽象的内容形象化，提高学生的学习兴趣，本文以MATLAB作为开发平台，设计了基于MATLAB的数字信号处理虚拟实验仿真平台，改变了传统的实验方式 ,将数字信号处理的实验内容集中在一个平台上，操作简单方便，结果直观准确。MATLAB开放的环境、功能极强的图形绘制、各种工具箱及其简单易学的特点，使系统开发简单、快捷。本系统采用友好的GUI界面设计,用简洁的文字、丰富的画面将抽象的内容展现在学生面前,提高了学生的学习积极性和主动性。 关键词: 数字信号处理；实验平台；MATLAB；GUI  The design of digital signal processing virtual experiment simulation platform based on Matlab Student:Huang Zhong-Ze Teacher: Li Xin Abstract : “Digital Signal Processing” is the important foundation course of electrical and communications professionals in university, the content is very abstracty and students are not easy to grasp. The other hand, teachers taught in some main contents not very convenient. Against such problems exist in teaching,to allow teachers to teach and students to learn. So abstract as figurative, Enhance their learning interest. This paper represents digital signal processing virtual experiment simulation platform using Matlab. It changes the traditional teaching methods and focus on the content of a platform. Operation is simple and convenient. Results is visual and accurate. Matlab provides an open environment, highly functional graphical rendering. Toolbox and its features is easy to learn, which make the system development simple and fast, The system uses a friendly GUI interface design, using simple language, rich picture will be displayed the abstract content in the front of the students and improved student’s learning enthusiasm and initiative.
