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.

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!

I bought my first copy of this essential text in 1976, and have never found a better reference source on the principles of grounding and shielding. Few engineers seem to understand the action of screened cables, especially, and chapter 2 gives an excellent introduction

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.

I build EEG sensors, and I started reading this book, expecting something like The Art of Electronics, except more detailed and covering only noise techniques. Instead, I got much, much more. The diagrams made *much* more sense than Horowitz and Hill's AOE, and the explanations were clear and consise. I was able to read it cover to cover in a weekend without getting bored from too much detail, and it had many many real measurements of noise in systems that made the information much more quantitative.

For instance, instead of saying "in order to get the most noise reduction, you need to use a shielded cable only grounded on one end", he says "a shielded cable grounded on one end has 84dB of attenuation to magnetic noise and much more for electric, while if the shield is grounded at both ends the attenuation is more like 36dB".

Those numbers are critical if you're trying to balance signal quality with cost.

One of the best textbooks I've ever purchased.

If you are a beginner or work in the EMC field, is the best book to start with. Many of other books have it as a reference. There is a new book from Mr Ott (2009) but I still haven't read it, in any case this one is a classic that is worth buying.

BOOK: NOISE REDUCTION TECNIQUES IN ELECTRONIC SYSTEMS
Depite this book has a lot of years, the basic principles have not changed and I find this book very instructive to learn things as types of noise, crosstalk, radiation, grounding and shielding techniques or cabling. Henry W. Ott and his book, are a reference in the world about noise control and EMC concepts.

Written in easy way to understand, with very little equations, I suggest that if you want to have a copy of one of the most famous books on this science, buy it

BOOK: ELECTROMAGNETIC COMPATIBILITY ENGINEERING
EMC topics are so complex that an expert is an expert because it acquires a high degree of specialization in a particular area of this science. This is the case with Mr. Ott, which I and many other people consider the world's number one expert in noise control in electronic circuits. He has a great ability as a communicator. I encounter fascinating his new book, it has given all the issues clearly. The book is well organized, easy to read and understand and you can jump from one chapter to another without losing any information. I highly recommend this book to all the people who want to learn more about this exciting science.

Item came on time. Good price. It's very nice to have one to read.
Good service and very nice to work with.

I greatly appreciate the practicality of this book. If you can't attend one of his seminars, my recommendation is to buy this book, it will help. It's one of those that I plan to keep in the EMC lab and not just on the shelf. -doug

Very good book, with little equations and down to Earth comments about issues EMC. Problem is that the book is from 1988 and all the initial discussion about FCC regulations is a bit outdated. Nevertheless it is a very good reference and I am glad I have it. Btw, I bought mine through one of Amazon's resellers so I dont have the pretty cover. I am not done reading it all but I am almost 1/2 way in and the material is very good.
