Double Degree in International Computer Engineering and Management of Business and Technology

Signals and Transmission Systems

Description
Every graduate in Engineering must have a knowledge and mastery of the fundamental principles on which disciplines such as analog and digital communications, signal and image processing, or acoustics are based, among others. The objective of the subject is to give an introductory and fundamental vision of the mathematical tools that allow analyzing analog and digital signals, converting from the analog to digital world, modeling and representing signal processing systems, or transmitting signals either baseband or modulated, and either in its digital or analog version. It is a subject, therefore, with a clear mathematical orientation but with a fundamental real and practical application in the field of engineering. For this reason, during each semester a practical frame of reference will be used where the contents presented throughout all the topics will be contextualized, and that will facilitate the understanding of them by the students.

Methodology

The course is taught in 2 or 3 teaching sessions each week, totaling 150 minutes per week.

The usual dynamics of each class will consist of a combination of theoretical explanations, usually followed by the performance of exercises that exemplify what has just been explained. Applied methodologies: master class (MD0), problem class and exercises (MD1).

In addition, sessions will be dedicated to the contextualization of the contents in a practical framework (SalleTone and SalleRadio) and to the realization of demonstrations, analysis and visualizations of theoretical concepts using scripts and Matlab functions developed by the teachers with this aim. Applied methodologies: self-paced learning (MD5) and case method (MD13).
