Objectives

• Know the methods and physical / mathematical techniques to study the properties of signals and major in physics and engineering systems.

• Understand the key characteristics of linear systems and time invariant (LTI).

• Mastering the behavior of LTI systems actuated by continuous or discrete signals, including the real situation in which the signals are degraded by the presence of noise.

• Understand the basic principles of control systems and the techniques and procedures used for their study.

• Understand the wide field of application of the principles, methodologies and techniques studied.

• Acquire skills that enable work effectively in applications involving systems as well as to pursue further studies in this area.

Learning outcomes and competences

We intend this course to give a clear, modern vision of the techniques used in the study of signs and particular sistemas.Em are studied Fourier series, integrals Fourier Transform FFT and Laplace of continuous and discret signals of tim..O concept of transfer function is critical and studied in detail as well as the  impulsional response.Sistemas Communication systems are also studied as well as the Shannon theorem.

Calculation formula of final grade

The test mark provides exemption from examination if is equal ou superior to 9.5/20. If the student in these circumstances is present at final examination the final mark is the majorant of the two.
