The Engineer's Mini Notebooks are great for electronic hobbyists, who want to study and build all types of circuits, and they include really wonderful ideas for science fair projects.This book will help both electrical and computer engineers generate ideas to build circuits. There are so many analog & digital logic circuits than purely analog circuits described in this book. The book has a few equations to describe the analog circuits (filters, oscillators, etc.), but lacks many that would help the reader can make the circuits meet certain specifications (i.e. equations that describes the frequency of oscillation or cutoff frequency on a filter, etc.) Therefore, it will help give you ideas to accomplish a task, but not be useful as a purely analog reference guide. Because digital circuits do not require equations, and the book is mostly digital, it makes for a good digital reference.
