It's a PDF and a very good one.  Just type in a relevant phrase, or word 
and you'll be there.  Start with RFI, or switching power supplies. 
That's where I'd start, but the whole thing is a good read, full of 
useful information.

I have the ARRL handbook, Antenna handbook, periodicals.  It's so easy 
to find things in this format all I have to do is bring up the document 
of interest, type what I want, and read.  It's not like lugging 15 to 20 
pounds of books and stacks of magazines, going through indexes and 
sorting articles.
