Way of continuous check of knowledge in the course of semester

V průběhu semestru se budou studenti aktivně zapojovat do řešení příkladů v rámci cvičení. Budou své znalosti aplikovat při laboratorním měření. V zápočtovém týdnu vypracují test obsahujícího 10 stručných otázek a dva příklady k řešení.
