- Learning outcomes of the curricular unit
On successful completion of this course, students will be able to:
- Analyze continuous-time signals in time domain and in frequency domain using Fourier series and Fourier transform.
- Analyze continuous-time linear time-invariant (LTI) systems and recognize their properties.
- Use MATLAB to process and represent signals in time and frequency domain.
- Use MATLAB to represent LTI systems in time domain and to analyze the effects of LTI systems using the frequency domain.
I. Continuous-time signals and systems introduction
II. Signals classification, Elementary signals, and basic operations on signals
III. Signal spectra: Fourier series and Fourier transforms of continuous-time signals.
IV. Linear and time invariant (LTI) systems
VI. Time and frequency representation for LTI systems.
VII Ideal Filtering, Amplitude and phase distortion
VIII Sampling and Reconstruction of continuous-time signals
- Demonstration of the syllabus coherence with the curricular unit's objectives
This course covers fundamentals of signal and system analysis. Topics include analysis in time and frequency domain of continuous-time signals (Fourier series and transforms), and of linear and time invariant (LTI) systems. MATLAB is used as a tool to study these topics.
- Teaching methodologies
The teaching methodology is developed in several components:
T – 45 theoretical teaching contact hours - Presentation and discussion of theoretical concepts, interactivity and asking questions are encouraged;
PL - 22.5 laboratory practice contact hours: Theoretical concepts are further developed through the implementation of practical examples, performed in groups.
The individual final results are assessed with a final examination given at the end of the semester, with MATLAB-based assignments during the semester
- Demonstration of the coherence between the teaching methodologies and the learning outcomes
In theoretical classes, syllabus content is presented, which match the learning outcomes 1 and 2.
In laboratorial classes, which match the learning outcome 3 and 4, students practice in the MATLAB tool the techniques associated with learning outcomes 1 and 2.
