Intended learning outcomes (Knowledges, skills and competencies to be developed by the students)

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.

Demonstration of the syllabus coherence with the UC intended learning outcomes

The syllabus presented is the theoretical support needed for the analysis and simulation of electrical signals and systems and also for the use of specific software. The concepts and methodologies of signal analysis are those that are available in most applications to be presented to students of this curricular unit.

Teaching methodologies

The teaching methodology to use in this course is based on the lecture method and simulation work. It will be used the Information System of ESTSetúbal/IPS and/or the Moodle platform to support teaching, particularly as a repository of information, delivery of work and tests for self evaluation and summative evaluation.

Demonstration of the teaching methodologies coherence with the curricular unit's intended learning outcomes

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 ofe-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.).

Assessment methodologies and evidences

Distribution assessment with final exam
The evaluation of the curricular unit consists in the accomplishment of laboratory works (to be realized in the classes) and of final exams. In order to obtain approval, students must obtain a mark in the evaluation works and the exams of more than 8.5 values. The papers have a weight of 40% in the final grade and the exams of 60%.
As an alternative to final exams, students will be able to perform continuous assessment with two tests. The minimum mark in each test is 8 out of 20.
Students will be allowed to take only one of the parts in the Normal Season exam, guaranteeing the grade obtained in the test for the other party. The student should choose whether to be assessed on the whole subject in the exam or if only to one of the parties, before the distribution of the statement.

Nfinal = 0.6 * NEx + 0.4 * NT
Being:
Nfinal - final grade;
NEx - exam grade;
NT - Note of the works

Observations

In addition to face-to-face contact in the classroom and at times of doubt, students can also communicate with the faculty through the Moodle e-learning platform and by e-mail at: jose.luis.sousa@estsetubal.ips .pt.
Support hours:
Monday at 4:30 p.m.
Tuesdays at 2:30 p.m.
