• Fourier and Laplace Transforms Coverage

← Back to Fundamentals of Electric Circuits Overview

• Fourier and Laplace Transforms Coverage

To ease the transition between the circuit course and signals and systems courses, Fourier and Laplace transforms are covered lu cidly and thoroughly. The chapters are developed in a manner that the interested instructor can go from solutions of first-order circuits to Chapter 15. This then allows a very natural progression from Laplace to Fourier to AC.

• Four-Color Art Program

An interior design and four-color art program bring circuit drawings to life and enhance key pedagogical elements throughout the text.

• Extended Examples

Examples worked in detail according to the six-step problem solv ing method provide a road map for students to solve problems in a consistent fashion. At least one example in each chapter is devel oped in this manner.

• EC 2000 Chapter Openers

Based on ABET’s skill-based CRITERION 3, these chapter openers are devoted to discussions as to how students can acquire the skills that will lead to a significantly enhanced career as an engineer. Be cause these skills are so very important to the student while still in college as well after graduation, we use the heading, “Enhancing your Skills and your Career. ”

• Homework Problems

There are 580 new or revised end-of-chapter problems and changed practice problems which will provide students with plenty of practice as well as reinforce key concepts.

• Homework Problem Icons

Icons are used to highlight problems that relate to engineering de sign as well as problems that can be solved using PSpice, Multisim, KCIDE, or MATLAB .

Organization

This book was written for a two-semester or three-quarter course in linear circuit analysis. The book may also be used for a one-semester course by a proper selection of chapters and sections by the instructor. It is broadly divided into three parts.

  • Part 1, consisting of Chapters 1 to 8, is devoted to dc circuits. It covers the fundamental laws and theorems, circuits techniques, and passive and active elements.
  • Part 2, which contains Chapter 9 to 14, deals with ac circuits. It introduces phasors, sinusoidal steady-state analysis, ac power, rms values, three-phase systems, and frequency response.
  • Part 3, consisting of Chapters 15 to 19, are devoted to advanced techniques for network analysis. It provides students with a solid introduction to the Laplace transform, Fourier series, Fourier trans form, and two-port network analysis.

The material in the three parts is more than sufficient for a two-semester course, so the instructor must select which chapters or sections to cover. Sections marked with the dagger sign (†) may be skipped, explained briefly, or assigned as homework. They can be omitted without loss of continuity. Each chapter has plenty of problems grouped according to the sections of the related material and diverse enough that the instructor can choose some as examples and assign some as homework. As stated ear lier, we are using three icons with this edition. We are using to de note problems that either require PSpice in the solution process, where the circuit complexity is such that PSpice or Multisim would make the solution process easier, and where PSpice or Multisim makes a good check to see if the problem has been solved correctly. We are using to denote problems where MATLAB is required in the solution process, where MATLAB makes sense because of the problem makeup and its complexity, and where MATLAB makes a good check to see if the problem has been solved correctly. Finally, we use to identify problems that help the student develop skills that are needed for engineering design. More difficult problems are marked with an asterisk (*).

Comprehensive problems follow the end-of-chapter problems. They are mostly applications problems that require skills learned from that particular chapter.

Prerequisites

As with most introductory circuit courses, the main prerequisites, for a course using this textbook, are physics and calculus. Although familiar ity with complex numbers is helpful in the later part of the book, it is not required. A very important asset of this text is that ALL the mathemati cal equations and fundamentals of physics needed by the student, are included in the text.

Acknowledgments

We would like to express our appreciation for the loving support we have received from our wives (Hannah and Kikelomo), daughters (Christina, Tamara, Jennifer, Motunrayo, Ann, and Joyce), son (Baixi), and our extended family members. We sincerely appreciate the invaluable help given us by Richard Rarick in helping us make the sixth edition a significantly more relevant book. He has checked all the new and revised problems and offered advice on making them more accurate and clear.

At McGraw-Hill, we would like to thank the following editorial and production staff: Raghu Srinivasan, global brand manager; Vincent Bradshaw, product developer; Nick McFadden, marketing manager; and Melissa Leick, content project manager.

The sixth edition has benefited greatly from the many outstanding individuals who have offered suggestions for improvements in both the text as well as the various problems. In particular, we thank Nicholas Reeder, Professor of Electronics Engineering Technology, Sinclair Community College, Dayton, Ohio, and Douglas De Boer, Professor of Engineering, Dordt College, Sioux Center, Iowa, for their detailed and careful corrections and suggestions for clarification which have
