电子MATLAB在信号分析中的应用.doc

摘 要 随着当代计算机技术的不断发展，计算机逐渐融入了社会生活的方方面面。计算机的使用已经成为当代大学生不可或缺的基本技能。信号与系统课程具有传统经典的基础内容，但也存在由于数字技术发展、计算技术渗入等的需求。在教学过程中缺乏实际应用背景的理论学习是枯燥而艰难的。 为了解决理论与实际联系起来的难题国内外教育人士目光不约而同的投向一款优秀的计算机软件——MATLAB。通过它可用计算机仿真，阐述信号与系统理论与应用相联系的内容，以此激发学习兴趣，变被动接受为主动探知，从而提升学习效果，培养主动思维、学以致用的思维习惯。 以MATLAB为平台开发的信号与系统教学辅助软件可以充分利用其快速运算，文字、动态图形、声音及交互式人机界面等特点来进行信号的分析及仿真。运用MATLAB的数值分析及计算结果可视化、信号处理工具箱的强大功能将信号与系统课程中较难掌握和理解的重点理论和方法通过概念浏览动态演示及典型例题分析等方式，形象生动的展现出来，从而使学生对所学知识理解更加透彻。同时运用教学软件中的数值计算工具箱，将学生从大量繁琐的手工数学运算中解放出来，将更多时间留给对基本概念和基本方法的思考。 关键词：信号与系统，，应用分析ABSTRACT As the modern computer technology development, computer gradually merged with the various aspects of social life. the use of the computer has become an essential part of the basic skills of students. the signal and systems of traditional classic of course, but there is also due to a digital technology development, the technology in the demand. in the teaching process of the practical application of theoretical study is boring and difficult. Theory with practice in order to solve the problem of educational circles and looked into a simultaneous of computer software — — matlab. it can be used by computer simulations, signals with the system theory and application related to the content, it aroused interest in learning and became passive acceptance of the initiative and thereby elevate learning, training of active in the habit of thinking, thinking. To the platform of the development of matlab signal system of teaching and assistive software can make full use of its rapid operation of graphic, text, dynamic and interactive voice man-machine interface to the characteristics of the analysis and emulation.
