Synopses & Reviews
This book attempts to answer the questions, “Why are we doing this?” and “What is this used for?” when applied to analog electronics. Since most people do not see where or how analog electronics fit into their lives, this book discusses several demonstrations and design examples with the express purpose of showing some of the cool things that can be done with analog electronics. This book generates engaging real-world examples that show readers where analog electronics fit into the overall engineering picture, raises their interest in electronics, and illustrates some of the basic principles. Covers circuit design from several aspects–theory, simulation, practical considerations, and lab verification. Design examples include: Stun Gun; Magic Feedback Audio Amplifier; Infrared Bug Sucker; Birthday Candle Blower; Klingon Pain Stick; and Electronic Hotdog Cooker. For non-technical users of electronics.
