A comprehensive text designed for students following a City and Guilds 2240 course in Electronics Servicing (part 1). It is supported by numerous worked examples, and multiple-choice exercises which follow the style of the City and Guilds examinations. The author has made use of his classroom experience in this area, and introducies concepts through everyday analogies, anticipating students' queries and problems. The inclusion of a chapter on fault-finding makes this book a useful accompaniment to the Level 2 NVQ in Servicing Electronic Systems.
