Planned learning activities and teaching methods
Lectures are lead with the massive support of Power-Point. The Power-Point file is available for students. In laboratories, students measure 11 exercises (electronic circuits) with the help of oscillograph. Numerical exercises do not exist - instead of it, the collection of cca 50 solved examples is available for student.
