First Sentence:
This chapter is devoted to cabling and cable shielding, and Chapter 3 covers grounding.
This updated and expanded version of the very successful first edition offers new chapters on controlling the emission from electronic systems, especially digital systems, and on low-cost techniques for providing electromagnetic compatibility (EMC) for consumer products sold in a competitive market. There is also a new chapter on the susceptibility of electronic systems to electrostatic discharge. There is more material on FCC regulations, digital circuit noise and layout, and digital circuit radiation. Virtually all the material in the first edition has been retained. Contains a new appendix on FCC EMC test procedures.

Reviews:
There is a specific topic in this book that I have not seem covered in any of the 25+ book that I have on electromagnetic phenomena. The topic is the shield cut-off frequency of a coaxial cable. Common-mode currents at low frequencies (below a few hundred hertz) cause noise problems with coaxial cables, but signals above tens of kilohertz do not. This is vital data which is apparently not explained in many text books. For me, this topic justifies the cost of the text. Having said that, I am annoyed because the book is quite expensive relative to other books of its size and age. The point is that you have to buy it, but it is expensive to do so.
Even an advanced designer will benefit from this book, although you, like me, won't necessarily want to read all of it. It is sufficient to pick and choose areas of particular interest. The less advanced designer would clearly benefit more and the book would therefore represent better value for them. Given a choice between this one and Morrison's Grounding and Shielding Techniques in Instrumentation, pick this one. This one is more technically accurate and useful.
If you take the course then you get the book too. And, since Ott is a good lecturer, you will likely learn a lot more than trying to read the book. For packaging engineers like myself, this book is not worth the money. You would be better off buying Blackwell's "The Electronic Packaging Handbook" which has an excellent chapter covering all important aspects of EMC. For Electrical Engineers I suspect what you have in your "High Speed Digital Design" (Johnson and Graham) will be more than adequate. The real issue is simply too much information. I agree with Ott that some understanding of antennas is needed to understand EMC but not nearly the amount covered in this book. I think that Ott's ham radio hobby has caused him to overdo that material in this book. I highly recommend taking the course but I suspect if you buy the book you won't finish reading it.
Henry Ott provides an excellent reference in "Noise Reduction Techniques in Electronic Systems". It is a comprehensive look at the sources of EMI in electronic circuits and also provides valuable insights into the reduction/elimination of the noise interference to meet the applicable test standards. It is must-read for novice engineers and a great refresher for the more experienced designer. No EMC engineer or system design engineer worth his/her salt should be missing this volume on their bookshelf!
