南京师范大学泰州学院毕业论文（设计）（2012届）题目：基于MATLAB的语音滤波器设计院（系、部）：电力工程学院专业：电气工程及其自动化姓名：严忠晨学号13080436指导教师：叶彪明南京师范大学泰州学院教务处制基于MATLAB的语音滤波器设计摘要走进新时代，科学急速发展，数字技术带来的生活日新月异。本文借着数字信号处理之手，结合先进的数学软件MATLABR2009a，对数字滤波技器的发展前景做出自己的分析理解推导。数字滤波器分为IIR和FIR两类。本着“求同存异”的原则，去繁化简，做出有一定程度和效果的创新总结。文中深入分析了滤波器系统设计的各个功能特点、实现原理以及技术关键，分别阐述了使用MATLAB进行带通滤波器设计及仿真的具体方法。从初学者的角度，篇幅中简单介绍了MATLAB，减少了“学院式”的理论推导，降低了Fourier变换、Laplace变换、z变换、复变函数的环路环节的理解难度，着力体现以“必须够懂为度”的原则。关键词：数字滤波器IIRFIRMATLABBasedOnTheMatlabVoiceFilterDesignAbstractWegointoaneweraandthesciencedevelopsrapidly.Thedigitaltechnologybringsthelifechangeswitheachnewday.Thisarticleisborrowinghandofthedigitalsignalprocessing,WithadvancedmathematicssoftwareMATLABR2009a,Makesowntothedigitalfiltertechniqueprospectsfordevelopmentanalysisunderstandinginferentialreasoning.DigitalfiltersaredividedintotwotypesofIIRandFIR.Inlinewith“seekscommongroundwhilemaintainingdifference”principle,Goestothenumeroussimplification,Sothatthereisacertaindegreeandeffectoftheinnovativesummary.Inthearticlehasthoroughlyanalyzedthefiltersystemdesigneachfunctioncharacteristic,Realizationprincipleaswellastechnicalkey,elaboratedseparatelyusesMATLABtocarryontheband-passfilterdesignandthesimulationconcretemethod。Fromtheperspectiveofascholar，lengthinthebriefintroductiontoMATLAB，reducethe"college-derivedfromthetheory."andtheFouriertransformation、theLaplacetransformation、theztransformation、complexvariablefunctionringcircuitlinkunderstandingdifficulty。Weshouldfocusoninthe"mustbeunderstoodastheprinciple."Keywords:DigitalfilterIIRFIRMATLAB目录摘要.....................................................................................................................IABSTRACT........................................................................................................II第一章绪论..........................................................................................................11.1数字信号处理概述...........................................................................................................11.2数字信号处理含义及学科...............................................................................................11.2.1数字信号处理含义................................................11.2.2数字信号处理学科................................................11.3数字信号处理系统特点...................................................................................................11.4数字信号处理实现方法...................................................................................................21.5本章小结..........................................................................................................................2第二章MATLAB概述........................................................................................32.1MATLAB简介...................................................................................................................32.2MATLAB特点...............................................................
