Teaching Methodologies and Assessment Criteria Lectures for exposition and development of the syllabus, accompanied by the presentation and discussion of application examples.
Laboratory classes to apply the theory exposed in the lectures. The proposed laboratory assignments, besides illustrating the theoretical concepts, allow the students to understand some practical problems inherent to its implementation. In the lab sessions, the students use EDA tools to capture and simulate the circuits, that, later on, they will implement on breadboards.

Final Grade = Assessment of the theoretical component (70% weight) + Continuous assessment of laboratory component (30% weight; a minimum score of 10 of a total of 20 is mandatory).

The assessment of the theoretical component consists in the completion of an one term test (during the teaching-learning period) or a final exam. The student will be exempted from the final exam, if the final grade of teaching-learning period is greater than or equal to 10 of a total of 20.
Language Portuguese. Tutorial support is available in English.
