Summary
Introduce participants into technology of electronic production with concentration on aspects of production the measurement and control instruments.
Subject gives the basic knowledge of methods relevant for construction of the electronic instruments. There are explained requirements on sources, input circuits, output circuits and control circuits in electronic devices. Participants will be familiar with selected technologies at design and production of electronic devices. Component of the course is practical realization within scope Half-yearly work. The study knowledge tend to be renew by excursions the enterprises, research institutes and project organizations.
Compulsory literature:
Recommended literature:
Way of continuous check of knowledge in the course of semester
Verification of study:
Content and form of assessed works:
Essay: Technical exposition fabricated on the base of minimally three sources (two of them must be of foreign origin and language) at the theme in accordance of student's selection, must be approved by lecturer. It has to comprise annotation at the beginning and the bibliography at the end (arranged in accordance with valid standards). The layout is given at the beginning of the semester.
Half-yearly work: Solving of the more extensive problem (design of scholastic prototype of electronic equipment) includes realization of the hardware and software components. The documentation of prototype must contain the comprehensive problem solving description. The vindication is successful, when the student presents his own result, explains independently function, presents whole documentation of the solving method, including theory, including constructional and project arguments and including function verification and comments how the assignment was fulfilled. Student must be able the half-year work to publicize by locating on the WEB server.
