This handbook outlines the factors that must be considered in designing circuits, equipment, and systems for electromagnetic compatibility (EMC). It teaches circuit and system designers practical approaches to thwart the ever present culprit of electromagnetic interference (EMI). By emphasizing the fundamentals, it provides information that will help readers understand the rationale that forms the basis for many of the EMC practices and procedures. There is much information about these topics available in disparate forms (journal articles, symposia proceedings, etc.) but this book brings the critical knowledge into a single source for battling EMI.

The goal of all device and system designs that must function in an electromagnetic environment (i.e. radio, TV, radar, navigation, and communications) is to operate without adversely affecting other electronic equipment or systems. The inverse is also true. The requirement for sharing spectrum has reached international levels of concern and it must be dealt with in proportion to the safety and economic impact involved. Designing Electronic Systems for EMC outlines how.

Book review

This book is written for engineers looking to understand EMC from a practical standpoint. The chapters cover many of the key areas that someone involved in EMC is likely to encounter and provides enough information for the engineer to investigate individual topics at a detailed level. It also fits well with my objective of making students aware of EMC so they have the right kind of knowledge to deal with EMC issues as they affect the overall product design.

This book emphasizes fundamentals and provides information that will help the reader to understand the rationale that forms the basis for many of the EMC practices and procedures described.
