This ninth edition of Electronic Devices reflects changes recommended by users and reviewers. Applications and troubleshooting coverage have been expanded to include several new topics related to renewable energy and automated test programming. As in the previous edition, Chapters 1 through 11 are essentially devoted to discrete devices and circuits. Chapters 12 through 17 primarily cover linear integrated circuits. A completely new Chapter 18 covers an introduction to programming for device testing. It can be used as a “floating” chapter and introduced in conjunction with any of the troubleshooting sections. Chapter 19, which was Chapter 18 in the last edition, is an online chapter that covers electronic communications. Multisim® files in versions 10 and 11 are now available at the companion website, www.pearsonhighered.com/electronics.
New in This Edition Reorganizations of Chapters 1 and 2 These chapters have been significantly reworked for a more effective coverage of the introduction to electronics and diodes. New topics such as the quantum model of the atom have been added. GreenTech Applications This new feature appears after each of the first six chapters and introduces the application of electronics to solar energy and wind energy. A significant effort is being made to create renewable and sustainable energy sources to offset, and eventually replace, fossil fuels. Today’s electronics technician should have some familiarity with these relatively new technologies. The coverage in this text provides a starting point for those who may pursue a career in the renewable energy field. Basic Programming Concepts for Automated Testing A totally new chapter by Gary Snyder covers the basics of programming
