ABSTRACT摘要摘要滤波器是自动控制、信号处理和通信领域重要组成部分，广泛运用各个系统中。ADS（AdvancedDesignSystem）软件是安捷伦公司开发的电子设计自动化软件，功能强大，仿真手段丰富多样，并可对设计结果进行优化，是非常优秀的微波电路设计工具。它的版面计算功能和建模功能，能够精确的对滤波器的匹配电路进行优化和计算。本文是通过利用ADS自带的滤波器设计向导实现椭圆低通滤波器的设计，介绍了椭圆型滤波器的基本原理和设计理念，给出了基于ADS设计滤波器的基本步骤和怎么利用ADS对设计进行优化。关键词：滤波器设计，ADS，仿真AbstractABSTRACTFilterisanimportantpartofautomaticcontrol,signalprocessingandcommunications,widelyusedinvarioussystems.ADS(AdvancedDesignSystem)softwareiselectronicdesignautomationsoftwaredevelopedbyAgilent,powerful,meansrichanddiverse,andtooptimizethedesign,itisaverynicemicrowavecircuitdesigntools.Itslayoutcalculationandmodelingcapabilities,abletoaccuratelytooptimizefiltermatchingcircuitandcalculation.ThisisthroughtheuseofADS'sfilterdesignguideimplementationofellipticlow-passfilterdesign,introducesthebasicprinciplesandellipticfilterdesignconcepts,designbasedonADSfilterisgiventhebasicstepsandhowtouseyourADStooptimizethedesignKeywords:filterdesign,ADS,simulation电子科技大学成都学院本科课程设计（论文）目录目录TOC\o"1-3"\h\z\uHYPERLINK\l"_Toc418110696"第1章引言PAGEREF_Toc418110696\h1HYPERLINK\l"_Toc418110697"1.1背景和意义PAGEREF_Toc418110697\h1HYPERLINK\l"_Toc418110698"1.1滤波器的发展前景PAGEREF_Toc418110698\h1HYPERLINK\l"_Toc418110699"1.2滤波器的前景PAGEREF_Toc418110699\h2HYPERLINK\l"_Toc418110700"1.3本次的主要任务PAGEREF_Toc418110700\h2HYPERLINK\l"_Toc418110701"第2章LC滤波器PAGEREF_Toc418110701\h3HYPERLINK\l"_Toc418110702"2.1滤波器的介绍PAGEREF_Toc418110702\h3HYPERLINK\l"_Toc418110703"2.2滤波器的分类PAGEREF_Toc418110703\h3HYPERLINK\l"_Toc418110704"2.3滤波器的主要参数（Definitions)PAGEREF_Toc418110704\h4HYPERLINK\l"_Toc418110705"2.4滤波器的特性指标PAGEREF_Toc418110705\h5HYPERLINK\l"_Toc418110706"2.4.1特征频率PAGEREF_Toc418110706\h5HYPERLINK\l"_Toc418110707"2.4.2增益与衰耗PAGEREF_Toc418110707\h6HYPERLINK\l"_Toc418110708"2.4.3阻尼系数与品质因数PAGEREF_Toc418110708\h6HYPERLINK\l"_Toc418110709"2.4.4灵敏度PAGEREF_Toc418110709\h6HYPERLINK\l"_Toc418110710"2.4.5群时延函数PAGEREF_Toc4181
