Teaching language

Suitable for English-speaking students

Objectives

This course provides an introduction to electric circuit theory, basic analog electronics and digital systems.

Learning outcomes and competences

Upon successful completion of the course, the students should be capable of:

- applying Boolean algebra to logic problems;

- recognizing some basic relevant digital circuits and understanding their operation;

- building and testing basic digital circuits.

Training in Boolean logic, together with examples and solved exercises throughout the course, support the first two objectives. Experimental training provided by the laboratory assignments supports the last objective.

Working method

Presencial

Pre-requirements (prior knowledge) and co-requirements (common knowledge)

Arithmetic and logic.
