Extremely good book. As a practicing digital-electronics technician with no formal training (my major in college was cultural anthropology), I’ve hunted high and low for good electronics textbooks. This one is the best, bar none. No extraneous math, lots of insider’s information on the peculiarities of circuit design, and a huge range of topics covered clearly and thoroughly. So well written that I’ve had difficulty putting it down! Has a good index and bibliography and works well as a stand-alone reference book. As an introduction and workbook on today’s electronics it has no peer.
