Digital Electronics 5th Edition

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.

The book introduces the reader to digital signals and the applications of digital technology. It then covers binary and hexadecimal numbers and arithmetic. The circuits that are used in combinational logic are then considered, followed by sequential logic circuits. The book goes on to describe memories, programmable logic devices and visual displays. It concludes with analogue-to-digital and digital-to-analogue converters.

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. Key features

• comprehensive introduction to digital electronics
• fully-worked examples
• refers to practical devices throughout
• exercises with worked answers to numerical questions
• includes practical exercises for the student to carry out
• example circuits for use in Electronics Workbench available free from website ftp://ftp.awl.co.uk/pub/awl-he/engineering/green
• latest IEC symbols are used and explained

This text covers the digital electronic requirements of BTEC National Diplomas in Engineering. It will also be a useful text for introductory digital electronics modules on first year degree courses and BTEC Higher National Diplomas in engineering. it will also be suitable for C&G electronics servicing parts 2 and 3 (2240), NVQ information technology (C&G 7261) and electronics options on Advanced GNVQ Engineering.
