Books
Following are some books that may prove useful:
- Electronics For Dummies, Second Edition, by Cathleen Shamieh and Gordon McComb (Indianapolis: Wiley, 2009)—This is a good book to start with. It provides an introduction to electronics concepts, components, circuits, and methods.
- The Art of Electronics, Second Edition, by Paul Horowitz and Winfield Hill (New York: Cambridge University Press, 1989)—This is a useful reference book for designing circuits, as well as understanding the functionality of existing circuits.
- ARRL Handbook for Radio Communications 2012 (Newington, Connecticut: American Radio Relay League, 2012)—Although this is intended for ham radio enthusiasts, it is also a useful reference book for understanding circuit design. This handbook is updated every year, but if you buy the current edition, it should be good for several years.
