Electronic Testing and Fault Diagnosis is a comprehensive and highly practical guide to the theory and methods of testing electronic circuits and systems. The third edition has been fully revised to provide up-to-date coverage of standard test procedures, and reliability and maintainability analysis for most analogue and digital electronic components and circuits. An introduction to automatic test equipment (ATE) is included, as well as data on passive and active components. This book is a key course text for BTEC HNC/D and first year degree courses in electronics, as well as C&G electronics servicing (2240) part II/III. It is also suitable as a supplementary text for the fault diagnosis units of BTEC HNC science and GNVQ advanced engineering courses.
