Understanding Digital Troubleshooting: Third Edition; by Don L. Cannon. Sams, Division of Macmillan Computer Publishing, 11711 North College, Carmel, IN 46032, USA; Phone: 800-428-5331 or 317-573-2500; Fax: 800448-3804 or 317-573-2655; $24.95.

Digital systems must be effectively maintained if they are to operate reliably at peak performance levels. That is the central theme of Don Cannon's book on troubleshooting digital electronics. Mixing general tutorial information with "how to" instruction, the book is intended to help readers keep their digital circuits operating properly "in the pink." Intended for readers with a wide range of experience and formal technical background from the novice hobbyist to the experienced professionals, Cannon's book includes comprehensive text on basic electronic engineering concepts and the fundamentals of digital circuitry. After readers have learned (or refreshed their knowledge) of the fundamentals, they will be ready to start troubleshooting.

Cannon explains how to locate faults in digital circuitry and make repairs of increasing complexity on everything from simple control circuits to computers.

Chapters cover the techniques for troubleshooting with advanced timing techniques, analysis of serial, parallel, synchronous, and asynchronous circuits, signal tracing, and the use of logic clips and probes, and other specialized digital test equipment.

The book also covers the solution of problems in sequential logic circuits, how to test complex digital devices, and how to select logic analyzers and computer test equipment appropriate to the maintenance task at hand. Each chapter includes a self-quiz to permit readers to evaluate their progress and understanding of the subjects to which they have been introduced.
