It is equally well suited for use as a text that can support distance or flexible learning and for those who may need a ‘refresher’ before studying electronics at a higher level.While the book assumes little previous knowledge students need to be able to manipulate basic formulae and understand some simple trigonometry to follow the numerical examples.

You can use these end-ofchapter problems to check your understanding and also to give you some experience of the ‘short answer’ questions used in most in-course assessments.

For good measure, we have included 70 revision problems in Appendix 2.

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 to get started.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.At the end of the book you will find 21 sample coursework assignments.These should give you plenty of ‘food for thought’ as well as offering you some scope for further experimentation.In order to give you an appreciation of the solution of simple numerical problems related to the operation of basic circuits, worked examples have been liberally included within the text.
