Learning outcomes
|
The aim of the course is to build on the bachelor's degree courses Linear Electric Circuits and Computer Simulation of Electronic Circuits and to prepare students for the study of systems-related subjects as well as subjects devoted to advanced analog techniques and fast digital circuits. Emphasis is placed on the analysis and design of electronic circuits.
The student will acquire the ability to analyze the properties of electronic circuits and design circuits with the required electrical parameters. Emphasis is placed on circuit design.
