EMI Troubleshooting Cookbook for Product Designers is a one-stop guide that will help engineers and technicians who have products which fail to meet EMI/EMC regulatory standards. It provides "recipes" of simple, easily implemented, and inexpensive troubleshooting tools or aids that can be built by the engineer or the technician. Written in a very simple style requiring only minimal electromagnetic theory and math, the "cookbook" will teach the engineer and technician to develop a "process" for troubleshooting--making it a straight-forward approach to solving what may seem like a rather complicated problem. Real-world stories are used to further illustrate both the concepts put forth in the book and the thinking process required when troubleshooting EMI problems. All materials are organized around these main aspects in a logical way, providing accessible, useful, complete coverage of the main aspects of the mitigation/troubleshooting philosophy. The book's less technical approach and balanced coverage of both basic theory and practical aspects will provide guidelines on how to approach an EMI failure, things to try, choosing the appropriate component, to how to choose the right parts and balance between cost and performance.

The Keep It Simple (KISS) philosophy is the primary focus of this book. It is written in very simple language with minimal math, as a compilation of helpful EMI troubleshooting hints. Its light-hearted tone is at odds with the extreme seriousness of most engineering reference works that become boring after a few pages. This text tells engineers what to do and how to do it. Only a basic knowledge of math, electronics, and a basic understanding of EMI/EMC are necessary to understand the concepts and circuits described. Once EMC troubleshooting is demystified, readers learn there are quick and simple techniques to solve complicated problems a key aspect of this book. Simple and inexpensive methods to resolve EMI issues are discussed to help generate unique ideas and methods for developing additional diagnostic tools and measurement procedures. An appendix on how to build probes is included. It can be a fun activity, even humorous at times with bizarre techniques (i.e., the sticky finger probe).

Praise for Noise Reduction Techniques IN electronic systems "Henry Ott has literally 'written the book' on the subject of EMC. . . . He not only knows the subject, but has the rare ability to communicate that knowledge to others." —EE Times Electromagnetic Compatibility Engineering is a completely revised, expanded, and updated version of Henry Ott's popular book Noise Reduction Techniques in Electronic Systems. It reflects the most recent developments in the field of electromagnetic compatibility (EMC) and noise reduction¿and their practical applications to the design of analog and digital circuits in computer, home entertainment, medical, telecom, industrial process control, and automotive equipment, as well as military and aerospace systems. While maintaining and updating the core information—such as cabling, grounding, filtering, shielding, digital circuit grounding and layout, and ESD—that made the previous book such a wide success, this new book includes additional coverage of: Equipment/systems grounding Switching power supplies and variable-speed motor drives Digital circuit power distribution and decoupling PCB layout and stack-up Mixed-signal PCB layout RF and transient immunity Power line disturbances Precompliance EMC measurements New appendices on dipole antennae, the theory of partial inductance, and the ten most common EMC problems The concepts presented are applicable to analog and digital circuits operating from below audio frequencies to those in the GHz range. Throughout the book, an emphasis is placed on cost-effective EMC designs, with the amount and complexity of mathematics kept to the strictest minimum. Complemented with over 250 problems with answers, Electromagnetic Compatibility Engineering equips readers with the knowledge needed to design electronic equipment that is compatible with the electromagnetic environment and compliant with national and international EMC regulations. It is an essential resource for practicing engineers who face EMC and regulatory compliance issues and an ideal textbook for EE courses at the advanced undergraduate and graduate levels.

GROUNDS FOR GROUNDING The first book to cover grounding from the circuit to system and across the entire spectrum of applications Grounds for Grounding provides a complete and thorough approach to the subject of designing electrical and electronic circuits and systems, blending theory and practice to demonstrate how a few basic rules can be applied across a broad range of applications. The authors begin with the basic concepts of Electromagnetic Compatibility (EMC) that are essential for understanding grounding theory and its applications, such as “ground loop,” which is one of the most misunderstood concepts in EMC. Next, they provide an introduction to grounding, including safety grounding, grounding for control of electromagnetic interference, and grounding-related case studies. Subsequent chapter coverage includes: Fundamentals of grounding design Bonding principles Grounding for power distribution and lightning protection systems Grounding in wiring circuits and cable shields Grounding of EMI terminal protection devices Grounding on printed circuit boards Integrated facility and platform grounding system Practical case studies are integrated throughout the book to aid in readers’ comprehension and each chapter concludes with a useful bibliography. Grounds for Grounding is an indispensable resource for electrical and electronic engineers who work with the design of circuits, systems, and facilities.

In 1996, enforcement of the mandatory European Union EMI/EMC (electromagnetic interference and compatibility) began. Before that time, many designers were just beginning to worry about "EMI problems". Now, 8 years later, the same old EMI problems are still with us, and some new ones have emerged as well. Anyone selling components or equipment of any sort in Europe and therefore the world for most globally based companies requires compliance with the EMC directive. There is no alternative. The information in this book enables faster, cheaper compliance.

This ready reference provides electrical engineers with practical information on accurate methods for measuring signals and noise in electronic circuits as well as methods for locating and reducing high frequency noise generated by circuits or external interference. Engineers often find that measuring and mitigating high frequency noise signals in electronic circuits can be problematic when utilizing common measurement methods. Demonstrating the innovative solutions he developed as a Distinguished Member of Technical Staff at AT&T/Bell Laboratories, solutions which earned him numerous U.S. and foreign patents, Douglas Smith has written the most definitive work on this subject. Smith explains design problems related to the new high frequency electronic standards, and then systematically provides laboratory proven methods for making accurate noise measurements, while demonstrating how these results should be interpreted. The technical background needed to conduct these experiments is provided as an aid to the novice, and as a reference for the professional. Smith also discusses theoretical concepts as they relate to practical applications. Many of the techniques Smith details in this book have been previously unpublished, and have been proven to solve problems in hours rather than in the days or weeks of effort it would take conventional techniques to yield results. Comprehensive and informative, this volume provides detailed coverage of such areas as: scope probe impedance, grounding, and effective bandwidth, differential measurement techniques, noise source location and identification, current probe characteristics, operation, and applications, characteristics of sources of interference to measurements and the minimization of their effects, minimizing coupling of external noise into the equipment under test by measurements, estimating the effect of a measurement on equipment operation, using digital scopes for single shot noise measurements, prediction of equipment electromagnetic interference (EMI) emission and susceptibility of performance, null experiments for validating measurement data, the relationship between high frequency noise and final product reliability. With governmental regulations and MIL standards now governing the emission of high frequency electronic noise and the susceptibility to pulsed EMI, the information presented in this guide is extremely pertinent. Electrical engineers will find High Frequency Measurements and Noise in Electronic Circuits an essential desktop reference for information and solutions, and engineering students will rely on it as a virtual source book for deciphering the "mysteries" unique to high frequency electronic circuits.
