| Course description |
| Electrical circuits, which modern instruments for biomedical measurements do not work without, is one of the subjects that should be learned by all students who are willing to develop these instruments in the future. In this course, students learn how to calculate the response of direct- and alternating-current circuits composed of resisters, capacitors, and inductors. |
