Teaching language

Suitable for English-speaking students

Objectives

Aims Presentation of the fundamentals of Signal Processing, either in a deterministic or stochastic point of view, with a special emphasis in the frequency domain. Fundamentals of non parametric spectral estimation. The main objective is to provide a comprehension of concepts and methods and its effective use in the analysis of computer simulated and experimental data.

Learning outcomes and competences

The course orientation emphasis is the understanding of the main concepts and methods, together with an effective use of the methods in synthetic and experimental data analysis. At the end of the semester, the students should be familiar with the fundamentals of  Digital Signal Processing, particularly the analysis in the frequency domain, and being able to:
1. Manipulate with ease the fundaments fundamentals of  signals and systems.
2. Know the properties and how to use the various transforms studied.
3. Describe the properties of a signal and a linear system  (in the time and frequency domain).
4. Describe and analyse the effect of sampling a signal, and the consequent implication in what regards real signals.
5. Implement FIR and IIR filters and analyse their effects in a critical way.
6. Use Matlab for the analysis of signals and systems.

Teaching methods and learning activities

The course includes classes for theory (T) and theory-practice (TP). The classes of type T are used for the presentation of concepts and methods, illustrated with a variety of examples. The classes of type TP are used for the resolution of problems and projects, with a strong computational component in a laboratorial environment using MATLAB (Matlab - Signal processing Toolbox).

Eligibility for exams

The course attendance has a compulsory component of practical assignments / projects, with corresponding submission of programs / scripts / reports required within the fixed schedules (min. 8 out of 20 marks). The students may have to perform an oral examination regarding the practical assignments.

Calculation formula of final grade

The final course mark will be based on the assignment component (40%) and the final exam (60%), with both having to reach a minimum level of 40% (8 marks on a 0-20 scale).
