Introduction to Electric Circuits, 8th Edition
January 2010, ©2010
The presentation is geared to readers who are being exposed to the basic concepts of electric circuits for the first time, and the scope of the work is broad. Students should come to the course with the basic knowledge of differential and integral calculus. This book endeavors to prepare the reader to solve realistic problems involving electric circuits. Thus, circuits are shown to be the results of real inventions and the answers to real needs in industry, the office, and the home. Although the tools of electric circuit analysis may be partially abstract, electric circuits are the building blocks of modern society. The analysis and design of electric circuits are critical skills for all engineers.

Professor Dorf has extensive experience with education and industry and is professionally active in the fields of robotics, automation, electric circuits, and communications. He has served as a visiting professor at the University of Edinburgh, Scotland, the Massachusetts Institute of Technology, Stanford University, and the University of California at Berkeley.
A Fellow of the Institute of Electrical and Electronic Engineers and the American Society for Engineering Education, Dr. Dorf is widely know to the profession for his Modern Control Systems, eleventh edition (Prentice Hall, 2008) and The International Encyclopedia of Robotics (Wiley, 1988). Dr. Dorf is also the coauthor of Circuits, Devices and Systems (with Ralph Smith), fifth edition (Wiley, 1992). Dr. Dorf edited the widely used Electrical Engineering Handbook, third edition (CRC Pres and IEEE press), published in 2008. His latest work is Technology Ventures, third edition (McGraw-Hill 2010).
James A. Svoboda is an associate professor electrical and computer engineering at Clarkson University, where he teaches courses on topics such as circuits, electronics, and computer programming. He earned a PhD in electrical engineering from the University of Wisconsin at Madison, an MS from the University of Colorado, and a BS from General Motors Institute.
Sophomore circuits is one of Professor Svoboda's favorite courses. He has taught this course to 5,500 undergraduates at Clarkson University over the past 30 years. In 1986, he received Clarkson University's Distinguished Teaching Award.
Professor Svoboda has written several research papers describing the advantages of using nullors to model electric circuits for computer analysis. He is interested in the way technology affects engineering education and has developed several software packages for use in Sophomore Circuits.
Increased use of PSpice and MATLAB: Significantly more attention has been given to using PSpice and MATLAB to solve circuits problems. It starts with two new appendices, one introducing PSpice and the other introducing MATLAB. These appendices briefly describe the capabilities of the programs and illustrate the steps needed to get started using them. Next the PSpice and MATLAB are used throughout the text to solve various circuit analysis and design problems. We pay particular attention to interpreting the output of these computer programs and checking it to make sure that it is correct. Frequently this is done in the section called "How Can We Check.. ." that is included in every chapter.
Revisions to improve clarity: The chapter covering the Laplace Transform and the Fourier Series and Transform, Chapters 14 and 15, have been largely rewritten, both to improve clarity of exposition and to significantly increase coverage of MATLAB and PSpice. In addition, revisions have been made through the test to improve clarity. Sometimes these revisions are small, involving sentences or paragraphs. Other, larger revisions involved pages or even entire sections.
More Problems The 8th edition contains 120 new problems bring the total number of problems to more than 1350. This edition uses a variety of problem types and they problems range in difficulty from simple to challenging, including:
Straightforward analysis problems
Analysis of complicated circuits.
Simple design problems.
Compare and Contrast
MATLAB and PSpice Problems
Examples Because this book is oriented toward providing expertise in problem-solving, we have included over 260 illustrative examples.This abundance of illustrative examples provide precise mathematical solutions to practical problems. Verification examples and verification problems illustrate useful techniques for checking solutions to the problems discussed in each chapter.
Design Examples, A Problem Solving Method, and "How can we Check.. ."Each chapter concludes with a Design Example that uses of the methods of that chapter to solve a design problem. A formal, 5-step Problem Solving Method is introduced in Chapter 1 and then used in each of the Design Examples. An important step in the Problem Solving Method requires that we check our results to verify that they are correct. Each chapter includes a section entitled "How can we Check ..." that illustrates how the kind of results obtained in that chapter can be checked to insure correctness.
Key Equations and Formulas You will find that key equations, formulas and important notes have been called out in a shaded box to help students pinpoint critical information.
Summarizing Tables and Figures The procedures and method developed in this text have been sulnmarized in certain key Tables and Figures. Students will find these Tables and Figures to be an important problems-solving resource.
Introduction to Signal Processing Signal processing is an important application of electric circuits. This book introduces signal processing in two ways. First, two sections(Sections 6.6 and 7.9) describe methods to design electric circuits that implement algebraic and differential equations. Second, numerous examples and problems through this book illustrate signal processing.
· The text includes hundreds of exercises and problems to reinforce material, with liberally provided hints and answers.
· Integration of PSpice and MATLABâ sections that show how to solve circuit problems provide strong technology inte-gration.
· Flexible text organization includes a flowchart demonstrating alternative chapter organizations that can accommodate dif-ferent course outlines without disrupting continuity.
