Objectives
In this subject the student will learn: to handle the main concepts and analytical tools for analysis and processing of deterministic discrete-time signals; to analyze continuous-time signals and systems; the main concepts on sampling signals. The student acquires the ability to apply analytical and computational tools to solve real signal processing problems.
Prerequisites
Main mathematical concepts:
- integrals and derivatives
- series, polynomials and polynomial fractions
- complex analysis
- graphical representation
Subject matter
1 Signal and Systems
2 Linear, time invariant systems
3 The Laplace transform
4 Z transform
5 Periodic signals and the Fourier series (DFT)
6 Discrete-time Fourier transform
7 The continuous-time Fourier Transform

Teaching method
Theoretical classes, practical classes and Labs. The practical class and th lab are integrated into one session where the conceptes introduced during th theoretical class are applied both from an analytical and an hands-on point of view. Each session covers a main subject.
Evaluation method
Approval in the course unit ''Signal Theory'' can be achieved through one of two alternative forms:
1. Average grade above 9.5 (on a 20 value scale) on 2 tests to be held during the semester.
2. A final exam (''recurso'') with a minimum grade of 9.5 . The grade on this exam will be the final grade.
A frequency assessement is not required to be admitted to the final exam.
Both the tests and the exam will have two components: ''theoretical/practical'' evaluation, and laboratorial evaluation. The lab evaluation will be based directly on the work performed during the lab classes. The lab component of the tests will have a weight of 25%.
Class attendance is free and will not be evaluated. At the end of each practice session an individual questionnaire on the activity carried out in class will be answered. Students who answer the questionnaire in class are exempted from performing the laboratory component of the corresponding tests.
As aide-memoire, students are allowed to bring to the the tests and the exam a single A4 sheet of paper with formulas, tables or lab work information, for instance. Mobile phones are not allowed.
