The links from this page take you to useful book suggestions - most of them
are book suggestions for electronics or programming in general.
These types of books are more useful in the long run as they give you a more solid grounding in fundamental techniques and these are books that I have found the most useful.
In the C programming link page you'll find the best books for C programming
- strangely enough the most useful is actually the smallest!
Books on C programming.
Author: Howard Johnson
the best book on practical
digital design solutions for noise and signal integrityand covers the practical
aspects of making a digital circuitry operate in the real world. It is
essential reading covering all aspects of designing systems and pcbs that work.
It covers decoupling, ground plane design, signal reflection, crosstalk, and noise problems which occur in high speed digital machines ( above 10 megahertz) but importantly it shows practical and real examples showing how to solve these problems.
Note: Even for a 10kHz clock the edges of that clock signal are at high frequency and are subject to noise and reflection so even there this book is a useful!

This is the best
all round book on electronics covering a vast amount of ideas and
information. Although this is University grade stuff the information is
presented in an informal and maths free way (as much as possible).
The emphasis is on showing how devices and systems work using practical ideas and concepts so learning is not just theoretical - but theory is there as well.
It is useful as a reference source of ideas as well as showing for all types of electroncs learning from basic devices to processor systems covering all kinds of circuits in between.
