| 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. The aim of this course is to learn direct- and alternating-current circuits composed of resisters, capacitors, and inductors, and become able to calculate the circuit response. |
