Elements of Electronics
- Department of Circuit Theory
The subject AE8B31ELE (B-ELE) is a free continuation of the subject AE8B32IES
(B-IES), now with technical contents yet, that provides elementary basis of electrical and electronic engineering, describes and explains common contexts among electrical phenomena, that are important for subsequent specialized subjects (for instance AE8B31CIR (B-CIR), AE8B31DIT (B-DIT), AE8B31EMT (B-EMT), AE8B31SAS
(B-SAS).). The subject education uses relatively simple, elementary mathematical and physical methods adequate to the 2nd semester of the bachelor study stage. The subject provides basis of:
- electromagnetic field and electrical circuit theory
- semiconductor components theory
- signal and system theory
- digital and microprocessor technique.
Solid knowledge of mathematics and physics specified in subjects
AE8B01LAG (B-LAG), AE8B01MC1 (B-MC1), AE8B02PH1 (B-PH1).
