Learning outcomes
|
This course follows Linear Electric Circuits and Computer Simulation of Electronic Circuits courses. The aim of the course (Analysis and Design of Electronic Circuits) is to prepare students for study of advanced analog and digital circuits, and to study the circuits on the boundary between analog and digital area. The emphasis is on analysis and design (synthesis) of electronic circuits.
After the study of this subject the student will be able to analyse electronic circuits characteristics and will be able to design electronic circuits with required electric characteristics (parameters). The emphasis is on circuit design.
