I'll keep this review short. I used this book for my first two years at University in 2001 and it certainly helped me get through my electronics modules. I knew nothing of electronics so this book is ideal for beginners to intermediate level. Like everything else, if you don't understand it the first time, read it again or use supplementary material. The book may be a bit out of date with regards to modern technology, but the basic principles remain the same for electronic components ie diodes, resistors. I graduated with a first so it certainly achieved its purpose for me. I still have this book, and from time to time I refer to it, which brought me back here as I was seeing if a new edition was available. I hope the author at one point will have time to do a new edition, but how can he keep up when a new iPhone or iPad comes out every 6 months!
