Base Knowledge
Derivation and integration rules.
Operations with complex numbers.
Teaching Methodologies
In the lectures is performed an oral presentation of mater with the support of slide projection. The theoretical exposure of concepts is complemented for formulating and solving some application exercises. The slides are available to students on the moodle platform. In the classes are solved exercises and matlab aplications are implemented.
Learning Results
To learn and understand basic theory of signals and linear systems wth continuous and discrete time and of using system representations based on the Fourier transforms.
To acquire the ability of analyzing and manipulating signals and linear time- invariant systems in both the time and frequency domains.
Students will learn and understand basis of description and analysis of discrete and continuous -time signals and systems.
