Quite a few years ago, I had the pleasure of attending a seminar on EMI/ESD etc given by Henry Ott PhD. At the time he may have still worked for Bell Labs ( or AT&T, I forget which it was then). They had a significant interest in types of noise -- and how to prevent them for minimum $$ given their massive nationwide system.
I still remember it as a very pleasant seminar primarily because Dr. Ott presented a lot of overview and practical understanding of various types of noise and how to deal with them. Included in the seminar was his book ( cleverly titled Noise Reduction Techniques in Electronic Systems). The lab guys referenced it a lot.
Anyway, I found a reference to his book on another forum and decided to see if it was still around. Not only is it still around (retitled Electromagnetic Compatibility Engineering), but so is Henry Ott -- and he's still doing seminars. He must love the work because I'm sure that he's in his 80's.
Here's his website if you care to check it out. I have no association with any of this, I just think that he knows what he's talking about.
Edit - but maybe I don't ! ( no maybe about this) Henry Ott is not ( and does not claim to be) a PhD. For some reason, I always thought that he was. I stand by my statement that he knows what he's talking about.
