Prerequisites and co-requisites
Signals and systems; Linear and Time Invariant Systems (SLITs); Laplace transform; Fourier transform; Time Response of Causal SLITs; Signal Sampling
The main objective of the course is to transmit to students the basic concepts of signals and systems as well as introduce the main mathematical and computational tools for their treatment. It is intended: - To introduce the fundamentals of Signal Theory and Linear and Invariant Systems in Time. In this way, the student will be able to understand, develop and design control systems, which can be applied to several areas of engineering. - To acquire the ability to analyze and manipulate linear and time invariant signals and systems through their representations in time, frequency, and Fourier and Laplace transforms. - Know how to use the most important tools for the treatment of numerical sequences. The application of these tools will allow the student to carry out high level analyzes, from the statistical treatment of communication networks or development and design of new algorithms.
Teaching methodologies and assessment
Theoretical teaching (T) - Presentation of the concepts defined in the programmatic contents. Practical teaching (P) - Presentation and discussion of the concepts defined in the programmatic contents and accompanied by the resolution of application examples. Guidance tutorial (OT) Follow-up of students in the resolution of exercises and supervision of other activities relevant to the course unit. Support for the study of small groups of students. - Periodic assessment: - Two individual written tests (PE1, PE2). PE = 0.5 * PE1 + 0.5 * PE2, PE> = 8 - Practical work (TP), TP> = 8 FINAL NOTE = 0.7 * PE + 0.3 * TP> = 10 - Final evaluation: - Individual written test (PE) > = 8 - Laboratory work (TP), TP> = 8 FINAL NOTE = 0.7 * PE + 0.3 * TP> = 10
