Quickly get a good understanding of "digital" (what it is, simplified
example, etc.). Ditto for "wireless," the "IC," how a transistor works,
and the other important things about electronics (even amplifiers,
pulse code modation, the dB, distortion and noise, etc., all SIMPLIFIED
and clarified). See the Customer Reviews in amazon.com that say this is
the EASIEST-to-read and EASIEST-to-understand of all the electronics
books for non-engineers. Just click on

and notice that amazon also has links for used copies of the book at
lower prices.
