Teaching methods/Media:
Slides, lab guides, exercises and videos; all materials can be accessed electronically by students. The module combines lecture and lab components. The lab component consists of 5 compulsory sessions. Experiments will be carried out in groups of two, preparation for the lab sessions will be checked individually. A report must be written for each of the lab experiments. These reports must be personally presented to the lecturer/supervisor. In the lab sessions, students will carry out various measuring tasks on real objects and devices without demonstration, but according to instructions. A supervisor will be available to assist them, if needed.
