Demonstration of the syllabus coherence with the UC intended learning outcomes

Matter of Chapters 1 and 2 ensure the ability to analyze and represent signals. The subject of Chapters 3 and 4 ensures the representation and modeling of systems. The contents of Chapters 5 and 6 develop the system analysis for their response in the time domain and frequency as well as the stability conditions. In chapter 7, the software tools used by students are powerful and actual tools for laboratory analysis of signs and systems

Teaching methodologies

Theoretical and Practical Lessons: presentation of concepts and application examples. Resolution of Exercises by students.Laboratories: signal analysis and circuit mounting for systems analysis and simulation.Computer simulation of systems and analysis of their responses (time and frequency), using software Matlab and Simulink.Evaluation: 2 tests during classes or final exam. Reports of laboratory work with a weight of 30%.

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

The existence of classes with theoretical and practical component is suited to the characteristics and content of this curricular unit. The concepts that must be learned and used require a careful exposition. The resolution of exercise strengthens their understanding. The existence of laboratory work is important to allow physical contact with the systems and viewing their responses on the oscilloscope and computer simulation.

Assessment methodologies and evidences

Assessment Type Distribution assessment with final exam Assessment Components

Continuous evaluation: - 2 tests
The minimum mark in each test is 8.0 points.
The theoretical grade (T) is obtained by the mean of the tests and must be greater than or equal to 9.5v.

Final exam (alternative to tests):
Classification should be greater than or equal to 9.5v (T).

Labs: Report delivery at the end of class: The grade (L) is given by the average report grade and must be greater than or equal to 9.5v.

The final grade is the weighted average of the two (T, L): NF = 0.7 T + 0.3 L
Final scores higher than 17 are defended in oral test.
___________________
Rules for taking tests:
• When requested, an identification document must be presented during the tests.
• Only written tests are accepted in ESTSetúbal test/examination sheets.
• The room can only be abandoned 30 minutes after the start of the test and implies the final delivery of the test, and the delay cannot exceed 15 minutes under any circumstances.
• Calculation machines with graphics or alphanumeric capabilities cannot be used during the tests unless the teacher explicitly authorizes them.
• During the tests, the handling or display of mobile phones (which must be switched off) and other electronic equipment is not allowed, and any of this type of equipment is used to cancel the test.
