    Rational Software Architect Workshop UML Diagrams What is a Model? • A model is a semantically closed abstraction of a subject system. – A model is defined in RUP as “a complete description of a system from a particular perspective.” • Examples of models: – UML model – Code – Data model Diagrams • Diagrams graphically depict a view of a part of your model. • Different diagrams represent different views of the system that you are developing. • A model element will appear on one or more diagrams. ...... Model Templates: Enterprise IT Design Model A design model describes the realization of use cases to design classes. Architectural Layers Separate business logic from data and user interface Use-Case Realization Shows how a use case is implemented in terms of collaborating objects

    切比雪夫滤波器设计 前言 人类正在进入信息时代,信号处理与滤波器设计是信息科学技术领域中一个不可或缺的重要内容。然而半个世纪以来,滤波器的设计的基本理论一直没有改变,现有的技术都只支持一种滤波器实现方法,像无源LRC滤波器、有源RC滤波器、数字滤波器、开关电容滤波器,从指标要求到实际设计的第一步,都是基于O.J.Zoble,R.M.Foster等许多前人的基础工作。由此而产生的设计理论导致了滤波器设计的初始设计的方程化;把给定的指标转化为S域或z域的传递函数,或转化为 LC滤波器结构。进行到这一步时,设计者可以选择滤波器类型,如切比雪夫滤波器,巴特沃思滤波器,椭圆滤波器或其他类型。选择什么类型有以下因素决定:滤波器阶数决定、群延迟、带内波纹、带边选择性,易于调试性及其它一些相关要求。 ...... 1] (日) 森 荣二著.LC滤波器设计与制作[M].北京:科学出版社,2006.1 [2]黄智伟. 全国大学生电子设计竞赛训练教程[M]北京:电子工业出版社出版,2005.1.90-91 [3] Miroslav D.Lutovac. 信号处理——滤波器设计[M]北京:电子工业出版社,2005.1.58 [4] 孙力维.电子滤波器设计[M]北京:科学出版社.2008.10 .26 [5]周利清.信号处理与引论.北京:电子工业出版社2005.4.100-240 [6]蔡明生.电子设计.北京:高等教育出版社.2004.1.255-258
