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 include lectures, computer laboratories and practical laboratories. Course is taking advantage of e-learning (Moodle) system. Students have to write two single projects and write laboratory protocols during the course.

Assesment methods and criteria linked to learning outcomes

The final evaluation of this subject consists of:

a) evaluation of laboratory protocols,
b) evaluation of individual PC projects,
c) evaluation of the test (a + b + c = 40 %),
d) assessment of the written and oral exam (d = 60 %).

The points ratio from particular parts of subject and the conditions for obtaining credit and tests are specified by the teacher at the beginning of the semester. Requirements for completion of a course are specified by a regulation issued by the lecturer responsible for the course and updated for every.
