"How is this different from The Art of Electronics?
The Art of Electronics is a wonderful book, but doesn't contain a lot of information about the design process. It's mostly theory, which is important, but is missing a lot of the information that I ended up learning the hard way. The Art of Electronics makes a wonderful companion to Designing Electronics that Work."
