Planned learning activities and teaching methods

Teaching methods depend on the type of course unit as specified in the article 7 of BUT Rules for Studies and Examinations. Techning methods are individual include including appropriate literature and practical laboratory measurements. Course is taking advantage of e-learning (Moodle) system. Students develop an individually assigned course project.

Assesment methods and criteria linked to learning outcomes

Course Project: max. 30 points.
Final Examination: max. 70 points.
