Our approach to the art of teaching circuits in our textbook differs from most others. We realize that electric circuits are intimately integrated into so much of our modern technology that many students from different disciplines need to learn about them. Studying circuits can be daunting, but interesting, practical, and rewarding. This can be true even for students who are not majoring in electrical or computer engineering. We believe that most students who pursue engineering studies wish to be creative and design things. Most circuits texts do not focus on this basic desire, rather spend their pages teaching why and how electric circuits work without affording the student an opportunity to put this learning into practice.
The longer it takes students to try their hand in designing things, the more likely it is that they will become disillusioned and frustrated perhaps even to the point of changing to a different major. We have long believed that an early introduction to design and design evaluation raises the excitement level and greatly increases student interest in their chosen discipline. Over 50 years of combined teaching experience at the USAF Academy, the University of Denver, the University of Colorado at Denver, and the Air Force Institute of Technology, has only served to strengthen our belief.
This new edition furthers this strategy by adding more design and evaluation examples, exercises, homework problems, and real-world applications. In addition, students today solve problems using computers, by hand, and with a calculator. Access to personal computers, laptops, notebook computers, and “smart” devices is nearly ubiquitous, and key software used in circuit analysis and design has become available for free or at very deep discounts for students. This edition of our text includes more software examples, exercises, and discussions geared to making the study of circuits more in line with the interests of today’s students. Our text has always included software, but generally as an extension for solving circuits by hand.
This edition continues our effort begun with the sixth edition by integrating software intimately into the solution of circuit problems whenever and wherever it really helps to solve the problems. It still recognizes that using software does not replace the intuition that engineers must develop to analyze, design, and make smart judgments about different working solutions or designs. The eight edition of The Analysis and Design of Linear Circuits improves on the seventh edition and remains friendly to users who prefer a Laplace-Early approach championed in our first edition, or those favoring the more traditional Phasor-First approach to AC circuits. A later section discusses how to use this text to pursue either approach using three different focuses. In this edition, we have added more skill-level examples, exercises, and problems that can help develop the student’s confidence in mastering the different objectives.
The eight edition assumes that the same student prerequisites as past editions and continues to rely on students having access to personal computers although computer access is not essential for using this textbook we believe it improves and expands learning. This edition targets students of all engineering disciplines who need an introductory circuit analysis course of one or two terms. The eight edition continues the authors’ combined commitment to providing a modern, different, and innovative approach to teaching analysis, design, and design evaluation of electric circuits. Every homework section ends with several integrating problems that test mastery of concepts that cover several objectives.
These more in-depth problems test whether the student not only has mastered individual objectives but also was able to integrate knowledge across several objectives. Our experience convinces us that an interweaving of analysis and design topics reinforces a student’s grasp of circuit analysis fundamentals. Early involvement in design provides motivation as students apply their newly acquired analysis tools to practical situations. Using computer simulation software to verify their designs gives students an early degree of confidence that they have actually created a design that meets stated specifications.
