Base Knowledge
Electric circuits analysis techniques
Teaching Methodologies
Theoretical classes: given in classic theoretical lecture classes, exposing the contents recurring to audiovisual resources and a blackboard
Theoretical-Practical classes: problem solving
Laboratory classes: experimental work with real components, applying and measuring signals with test equipment in order to assess the correct functioning of circuits and the role of semiconductor components. Implementation and test of circuits designed by students (of small complexity).
