Objetivos

This curricular unit aims to equip students from introductory knowledge in the areas thatpermits the analysis of electrical signals and systems. It is intended to introduce concepts and methods in the area of the signal processing and also the application of simulation tools in the analysis of electrical signals and systems.

Resultados de aprendizagem e competências

The main objectives of this discipline are associated with the development of skills to permit the signals and systems analysis with particular emphasis on the electrical signals and circuits. To consolidate the material taught in lectures, methods are used for exhibitions and simulation work in order to convey to students the essential knowledge to achieve the objectives. The use of e-learning platform Moodle promotes greater contact between the participating faculty and their students, either through forums or other activities that stimulate communication between elements (for self-assessment tests, availability of the classes, etc.).
