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. Teaching methods depend on the teaching methods are described in Article 7 of the Study and Examination Regulations of the University. Laboratory (numerical) is compulsory, properly excused absences laboratory exercises (maximum of two) can be arranged with the teacher substitute (usually in the credit week).
Techning methods include lectures, computer laboratories and practical laboratories. Course is taking advantage of e-learning (Moodle) system. Students have to write a single project/assignment during the course.
