Objectives

This course aims to equip students with the knowledge necessary for mastery of basic concepts, methods, techniques and tools for the identification, analysis and design of systems: - Acquisition of signals from the continuous domain to the digital domain, - Signal processing in the digital domain and - Translating the signals output to the continuous domain or other domains according to the application in question.

Learning outcomes and competences

After successful completion of the course the student is able to: Identifying, analyzing and projecting the following blocks: the sensor signal conditioning, analog-digital conversion, digital signal processing and analog-digital conversion by selecting the most appropriate technology for the application being treated. Understanding the mathematical representation of signals in the continuous domain, discrete and digital as well as their relationship. Understanding the mathematical representation of signals in the time domain and frequency as well as their relationship. Understand sampling and reconstruction of signals, including the implications and conditions that must be made. Understanding the meaning and use of Fourier transforms and Z. Analyze digital filters and projecting them through specified objectives. Apply the techniques of digital signal processing in control systems.

Teaching methods and learning activities

The lectures illustrate the issues to be discussed, using a philosophy of active learning, with examples of application and design of typical case studies. In laboratory classes are developed skills for mastery of tools and platforms for the implementation of digital signal processing in the real world. Integrating projects are also conducted to familiarize students with the potential applications of the knowledge acquired. The performance and behavior of students in these classes is evaluated (LC).

Eligibility for exams

Students will be admitted to the Final Exam (FE) if they attend practical classes and if they reach a minimum mark of EIGHT(8) out of TWENTY (20) in the laboratory component (LC).

Calculation formula of final grade

Final Mark will be based on the following formula: 0.6*FE + 0.4*LCx.
FE- Final Exam.
LCx - Laboratory Component with mark upper limited by the Final Exam.
LC- Laboratory Component.
The LCx mark cannot exceed the FE by more than 4 points: TLx = min(TL, EF+4)
To complete the course, students have to reach a minimum mark of 8 out of 20 in the Final Exam and in the laboratory component.
All of the components will be graded from 0 to 20 rounded to the unit.

Examinations or Special Assignments

None.

Special assessment (TE, DA, ...)

Working students, military personnel and students association leaders who did not attend to practical classes, will have to attend a practical exam.
