毕业论文(论文)LC带通滤波器的设计与仿真设计.doc

摘 要 随着电子信息的发展，滤波器作为信号处理的不可缺少的部分，也得到了迅速的发展。LC滤波器作为滤波器的一个重要组成部分，它的应用相当的广泛。因此对于它的设计也受到人们的广泛关注。如何设计利用简单的方法设计出高性能的LC滤波器是人们一直研究的课题。 本文从滤波器的基本概念着手，层层深入的介绍了LC带通滤波器的设计过程，按照滤波器的经典设计方法，运用前人得出的一些数据手册，通过对实例的研究，简单的设计出了LC带通滤波器。然后把设计出的电路在Multisim8.3.30软件上进行仿真，最后把得出的结果与通过用matlab 7.1中信号处理工具箱里专用的滤波器设计分析工具fdatool设计出的滤波器进行对比，得出方法的有效性。 关键词：LC带通滤波器设计 Multisim8 fdatool 仿真  ABSTRACT With the development of electronic information, signal processing filter as an indispensable part, has been rapid development. LC filter filter as an important part of its application of a broad. Therefore it is designed also to be peoples attention. How to design a simple way to design high-performance LC filter people had been studying the subject. From the basic concept of filter start layers of depth on the LC filter with the design process, in accordance with the filter of classical design methods, the use of their predecessors that some data sheet, through the example of the study, the simple Designed to bring the LC filter. And then design a circuit in Multisim8.3.30 software simulation, the results of the final and by using matlab 7.1 signal processing in the toolbox for the filter design analysis tool designed to filter fdatool compared draw The effectiveness of the method. Keywords: LC band-pass filter design Multisim8 fdatool Simulation  目 录 第一章 绪论..........................................................................1 1.1 滤波器简介...............................................................1 1.1.1 滤波器的概念....................................................1 1.1.2 滤波器的种类....................................................2 1.2 LC滤波器概述...........................................................4 1.2.1 LC滤波器的两种类型..........................................4 1.3 国内外滤波器的发展和研究现状.................................5 1.3.1 滤波器的发展状况.............................................5 1.3.2 国内外投入滤波器产业概况................................6 1.3.3 滤波器的前景...................
