Electronics: Principles and Applicationsprovides a concise, practical introduction to analog devices, circuits and systems. Like earlier editions, the Seventh Edition combines theory with real-world applications in a well-paced sequence, introducing students to such topics as semiconductors, op amps, linear integrated circuits, switching power supplies, electronic communications devices and DSP. The text prepares students to effectively diagnose, repair, verify, and install electronic circuits and systems, without overwhelming them with excessive theory. MultiSim examples are included for optional simulation activities, with MultiSim circuit files included on a bound-in CD ROM. Prerequisites are a command of algebra and an understanding of fundamental electrical concepts.
