Editorial Reviews Review "...well written and flows smoothly...provides electrical engineering students with a new perspective in applied electromagnetics and circuit design...highly recommended." (CHOICE, September 2006) "...well written and flows smoothly...provides electrical engineering students with a new perspective in applied electromagnetics and circuit design...highly recommended." (CHOICE, September 2006) Product Description A Landmark text thoroughly updated, including a new CD As digital devices continue to be produced at increasingly lower costs and with higher speeds, the need for effective electromagnetic compatibility (EMC) design practices has become more critical than ever to avoid unnecessary costs in bringing products into compliance with governmental regulations. The Second Edition of this landmark text has been thoroughly updated and revised to reflect these major developments that affect both academia and the electronics industry. Readers familiar with the First Edition will find much new material, including: * Latest U.S. and international regulatory requirements * PSpice used throughout the textbook to simulate EMC analysis solutions * Methods of designing for Signal Integrity * Fortran programs for the simulation of Crosstalk supplied on a CD * OrCAD(r) PSpice(r) Release 10.0 and Version 8 Demo Edition software supplied on a CD * The final chapter on System Design for EMC completely rewritten * The chapter on Crosstalk rewritten to simplify the mathematics Detailed, worked-out examples are now included throughout the text. In addition, review exercises are now included following the discussion of each important topic to help readers assess their grasp of the material. Several appendices are new to this edition including Phasor Analysis of Electric Circuits, The Electromagnetic Field Equations and Waves, Computer Codes for Calculating the Per-Unit-Length Parameters and Crosstalk of Multiconductor Transmission Lines, and a SPICE (PSPICE) tutorial. Now thoroughly updated, the Second Edition of Introduction to Electromagnetic Compatibility remains the textbook of choice for university/college EMC courses as well as a reference for EMC design engineers. An Instructor's Manual presenting detailed solutions to all the problems in the book is available from the Wiley editorial department. From the Publisher Deals with the topic of interference (electromagnetic compatibility) in electronic systems. It builds on basic undergraduate electrical engineering concepts and principles and applies them to the design of electronic systems that operate compatibly with other electronic systems and do not create interference phenomena. To facilitate classroom teaching it is divided in two parts. The first provides the basic principles and skills for review, while the second refers to applications and aspects of EMC design. --This text refers to an out of print or unavailable edition of this title.

今天在做一个博客转发的功能,就像新浪微薄转播的那个功能一样,有一个textArea,就是我们发微薄的那个框,别人的微薄都有一个转发的按钮,当我们点击这个转发按钮的时候,他的微薄就会进入到textArea中,看起来很简单的文本框赋值,其实难点就在于,这时候的光标是定位在最前面的。于是搜索了baidu,google,找到了 IE下面的方法 代码如下: var tea=document.getElementById(“文本框的ID”); var txt=textArea.createTextRange(); txt.moveEnd(“character”,0-tempText.text.lengt

1.引言     随着电子信息对抗系统、雷达系统、武器控制系统、指挥决策系统、通讯导航系统的发展与升级换代,在有限的频谱范围内,工作频率的高度密集甚至是重叠、单位体积内电磁功率密度的迅速增加、各种电子设备的电磁干扰和敏感度的不断提高。特别是作为对电磁环境有重大影响的载体上的天线,其类型与数量存在着增加的趋势。平台上的天线少则几部,多则十几部几十部,有的甚至达到天线林立的程度。这些状况造成载体内部及其周围空间的电磁环境越来越复杂,从而导致电磁兼容的问题日益突出。作为直接影响和制约系统电磁兼容性的天线,其电磁兼容问题,包括理论分析预测、设计技术和试验调试等自然成为关注的问题。     本文采用
