Warm up to EMC. On May 16-18, 2017, in partnership with IN Compliance magazine I will be presenting a three-day public  Electromagnetic Compatibility Engineering Seminar in Cocoa Beach, Florida (Orlando/Melbourne area), including  one-day (5/17/17) of concurrent EMC Exhibits. Includes, by popular request, a session on Pre-Compliance EMC Measurements.

This three-day intensive EMC seminar and exhibit covers the practical aspects of noise and interference control in electronic systems, and provides a working knowledge of EMC principles. Emphasis is on the cost-effective design of analog and digital systems. Commercial, industrial, medical, military, and aerospace aspects of EMC are emphasized. The amount and complexity of mathematics is kept to a minimum, and concepts are illustrated with examples of actual case histories.

Participants will obtain the knowledge necessary to design electronic equipment that is compatible with the electromagnetic environment, and is in compliance with national and international EMC regulations.

Topics covered include:

  • Cabling
  • Grounding Principles
  • Digital Layout and Grounding
  • High-Speed Digital Decoupling
  • Radiated Emission Control, both Common-Mode and Differential-Mode
  • Pre-Compliance EMC Measurements
  • Common-Mode Filters
  • Digital Transmission Lines
  • RF and Transient Immunity
  • Conducted Emission Control, both Common-Mode and Differential-Mode
  • Shielding Principles and Applications
  • Mixed Signal PCB Grounding and Layout

This seminar is directed towards electrical engineers, however, mechanical engineers, reliability and regulatory compliance engineers, technical managers, EMC test personnel, technicians, and others who need a working knowledge of electromagnetic compatibility principles will also benefit from attending.

In addition to the class notes, participants will receive a copy of both my latest 872 page award-winning* book, Electromagnetic Compatibility Engineering, published by John Wiley in 2009, and the Electromagnetic Compatibility EMC Pocket Guide by Ken Wyatt and Randy Jost, published by Scitech in 2013.

* Association of American Publishers “2009 PROSE Award” in the field of Engineering & Technology.

On Wednesday, May 17, 2017, we will welcome a small group of EMC companies who will exhibit their products and services. During breakfast, morning and afternoon breaks, and an extended lunch, course attendees will have time to visit exhibitors’ displays and connect with some of the industry’s top suppliers, including test laboratories, test equipment companies, and EMC component manufacturers. After Wednesday’s technical session, we will all get together at a reception sponsored by the exhibitors for some food, drink, and good EMC comradery.

Comments from a few previous seminar attendees:

  • “I had high expectations for this course, high enough to justify travel from the opposite side of the planet. Henry exceeded them all!”
  • “I learned a lot of what I thought I knew was wrong, and when it was right I learned why it was right.”
  • “EMC demystified! It’s not black magic as many claim.”
  • “Probably the most useful technical seminar I have ever attended. Should have learned this 20 years ago.”
  • “This is the best practical course available.”
  • “An excellent seminar presented by a pragmatic, knowledgeable, entertaining teacher.”
  • “Excellent course! Presented in a very understandable way, even for a mechanical engineer.”

Three Book EMC/Signal Integrity Library

January 29, 2012

Would you like to have a mini-library on the subject of EMC and Signal Integrity that covers the frequency range from DC to light. The following three books, all highly recommended, will accomplish that. All the books are very readable, with a minimum of mathematics, and as a bonus there is very little overlap between the material contained in each of the books. I refer to all three of these books regularly.

Three Book Mini EMC Library

Electromagnetic Compatibility Engineering, by Henry W. Ott, published by John Wiley & Sons in 2009 has won the PROSE Award from the Association of American Publishers for the best book published in 2009 in the category of Engineering and Technology. It is the most comprehensive book on the subject and is the first EMC book that you should read. In addition to the core subjects of cabling, grounding, balancing, filtering, and shielding that made my previous book, Noise Reduction Techniques in Electronic Systems, an international success (translated into six other languages), this new book includes additional coverage of equipment and systems grounding, switching power supplies and variable speed motor drives, digital circuit power distribution and decoupling, PCB layout and stackup, mixed-signal PCB layout, rf and transient immunity, power line disturbances, and simple pre-compliance EMC measurements. Written in an easy to read and understandable style, it’s full of real-life practical examples. This book contains eighteen chapters, six appendices, and 872 pages.

High-Speed Digital Design, by Howard Johnson and Marty Graham, published by Prentice Hall in 1993 picks up where Electromagnetic Compatibility Engineering leaves off, with respect to high-speed digital circuits. Despite its title, this is more an EMC book than a classical digital design book. Its subtitle, “A Handbook of Black Magic,” gives away its true nature. Besides containing much practical information on the EMC aspects of high-speed digital design, the book also contains useful information on various measurement techniques that can be used to measure such things as power-ground plane impedance, metastable states, etc. Subjects include transmission lines, terminations, vias, clock distribution, clock oscillators, ribbon cables and connectors, layer stackup, and power distribution. This book is considered by many as a “crossover book” covering both EMC and signal integrity. Everything in this book is easy to read and practical. A “must have” book if you are designing high-speed digital circuits! This book contains twelve chapters, three appendices, and 447 pages.

High-Speed Digital System Design, by Hall, Hall, and McCall, published by John Wiley and Sons in 2000 continues where the Johnson and Graham book ends. This is a signal integrity book! It is very well written with a good balance between theory and practical applications. The first sentence of the book sets the tone of the book; it reads, The speed of light is just too slow. Subjects include transmission line considerations, crosstalk, IC package and pin-out considerations, power delivery and decoupling, non-ideal current return paths, simultaneous switching noise, timing and skew considerations, and radiation. The book also includes a chapter on design methodologies useful in the design of high-speed systems with a large number of variables. As does the Johnson and Graham book, this book  contains a chapter on high-speed measurement techniques. The information contained in this book is useful at both the IC and PCB level. This book contains eleven chapters, six appendices, and 347 pages.


Want to expand your library by adding two additional books that fall on either end of the spectrum from the above three core books? Then consider the following two books:

Two Additional EMC Books

EDN Designer’s Guide to Electromagnetic Compatibility, Second Edition, by Bill Kimmel and Daryl Gerke, 2000 (originally published by EDN magazine in 1994), is a practical nuts and bolts approach to EMI, written for the non-EMI expert. One hundred pages of down-to-earth practical advice on EMC, without any equations or mathematics, by two authors who work regularly in the EMC trenches. The paperback book is available on the authors’ web site.

Introduction to Electromagnetic Compatibility, Second Edition, by Clayton Paul, published by John Wiley and Sons in 2006 is more theoretical than any of the other books, as it was intended to be used for a university course in EMC. A good book to get more detail on the theory behind EMC. Lots of useful information, especially the chapter on crosstalk, a subject that Dr. Paul is considered to be a leading expert. This book contains eleven chapters, four appendices, and 1016 pages.

So there you have it, three, (or possibly five) books that cover 90% of what you need to know about Electromagnetic Compatibility.
