Electronic Circuits: Fundamentals and Applications

Welcome! This is the book that I wish I had when I first started exploring electronics nearly half a century ago. In those days, transistors were only just making their debut and integrated circuits were completely unknown. Of course, since then much has changed but, despite all of the changes, the world of electronics remains a fascinating one. And, unlike most other advanced technological disciplines, electronics is still something that you can do at home with limited resources and with a minimal outlay. A soldering iron, a multi-meter, and a handful of components are all that you need. Except, of course, for some ideas to get you started—and that’s exactly where this book comes in!

The book has been designed to help you understand how electronic circuits work. It will provide you with the basic underpinning knowledge necessary to appreciate the operation of a wide range of electronic circuits including amplifiers, logic circuits, power supplies and oscillators.

The book is ideal for people who are studying electronics for the first time at any level including a wide range of school and college courses. It is equally well suited to those who may be returning to study or who may be studying independently as well as those who may need a quick refresher.
