Learning outcomes of the course unit

The student acquires concrete application knowledge of electronic instrument design, which is otherwise obtained only 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 parts of the design.


Basic knowledge of electrical engineering theory is required.
