The Science of Electronics: Digital

I like building circuits and playing with electronics. It is one thing to build a circuit board from scratch and solder all the pieces into place and quite another to understand WHY it works. I therefore recommend this book if you want to know WHY. I found it concise, easy to understand, and well presented. A very organized book which starts from first principles and introduces diodes, then BJT and FET and then Diff amps which is a natural segue into op amps and active filters. Plenty of worked examples and exercises to test your knowledge. Highschool math prerequisite. A very practical introductory book the hobbyist such as myself can understand and appreciate. Expensive which is why I gave it 4 stars.
