In the final examination of the training occupations in the electrical trade, the examinee is to show, among other things, that he/she can recognise and analyse customer wishes and problems and plan and design information and communication technology systems. Whereas in the past the technical knowledge was tested in individual questions and tasks, today the examination includes holistic tasks with a customer orientation. When working on tasks, protective measures as well as the relevant regulations must be observed and work processes must be planned and materials must be arranged. This book contains current questions, answers and tasks on all relevant examination contents in the field of electronics and information technology. The topics covered in the new edition range from fundamentals to circuitry, electroacoustics, image reproduction, digital storage media, communication technology, network technology, fibre optics, PC technology, high-frequency technology, digital cameras, measurement technology, regulations and environmental protection to customer advice and business processes. The project tasks deal with electronic circuits, receiving distribution systems, data networks, audio and video systems and telephone systems. The book contains both individual tasks and holistic tasks that are to be worked on in this or a similar form in the journeyman's examination in examination part A as well as in part B as system conception, customer advice and business process or in the technical discussion. This book thus enables targeted and effective examination preparation. The DVD supplement contains various documents for the project tasks in the book. It thus enables realistic and practical preparation in the field of equipment and systems engineering, as it is to be done in the examination and in practice. In addition, it contains sample solutions to the project tasks.
