Summary

Summary

This new title is based upon Trevor Linsley's successful Electronics for Electricians and Service Engineers and completely updates the previous text by taking into account the recent changes in the City and Guilds courses including 2240, 2360 and 2351. The new edition also incorporates hardware topics from the popular course, C&G 7261 Information Technology making this an indispensable reference for all those taking C&G courses. Trevor Linsley appproaches the subject in a practical, non-mathematical way, enabling both trainee and practising electricains and service engineers to relate electronics to their own experience. 'Electronic Servicing and Repairs' includes an expanded chapter on testing and fault diagnosis, incorporates PLCs and CAD software and introduces automatic text equipment (ATE). Communication and security systems are completely updated - the section on TV receivers, satellite TV, VCRs, CD players and cable TV has been expanded and a new chapter has been devoted to alarm systems.
