Aims

To be introduced to practicle principles of designing electronic instruments and devices as regards both electrical and mechanical aspects - in the industrial environment.
The student acquires concrete application knowledge of electronic instrument design, which is otherwise obtained through long-term development practice. Emphasis is laid on understanding the physical essence of parasitic events so that their knowledge can be applied to other cases. He learns to foresee and anticipate the appearance of many problems arising in the development of new instruments in both the electrical and the mechanical part of the design.

Specification of controlled education, way of implementation and compensation for absences

The content and forms of instruction in the evaluated course are specified by a regulation issued by the lecturer responsible for the course and updated for every academic year.
