Digital Electronics provides a comprehensive introduction to the principles of modern digital electronics from basic logic elements to analogue-digital converters. This new edition of Digital Electronics for Technicians has been revised to bring it up-to-date with current devices and includes many practical exercises. This book retains the traditional ideas which are still very relevant, particularly in teaching and prototyping. Each chapter starts with a list of objectives and also includes many fully worked examples and practical exercises. The exercises ask the reader to build a given circuit on a breadboard and test it to check its operation. A full list of the components required is given. The exercises use the readily-available and easy-to-use 74LS series devices but also give 74HC alternatives where they are available. There are also a series of Electronics Workbench circuit files available from Addison Wesley Longman's website that correspond to the practical exercises.
