This subject is articulated in the following specific competences:

- Understand different techniques for processing discrete signals and their representation in the frequency domain.

- Understand the analysis of continuous and discrete systems through its transfer function.

- Understand the fundamentals related to the capture, representation and coding of voice, audio, image and video.

- Manage basic techniques for the treatment of audio and image signals.

- Solve Telecommunication Engineering applications working with real multimedia information through cooperative laboratory practices.



This subject works the following cross-curricular competence:

Ability to solve problems with initiative, decision-making, creativity, and to communicate and transmit knowledge, abilities and skills, understanding the ethical and professional responsibility of the activity of the Technical Telecommunications Engineer.

PART 1: Signal processing tools

Topic 1: Discrete Fourier Transform (DFT)

Topic 2: Multi-frequency signal processing

Topic 3: Z-transform



PART 2: Voice and audio processing

Topic 4: Applications of audio processing

Topic 5: Voice codification

Topic 6: Voice synthesis and recognition



PART 3: Image and video processing

Topic 7: Basics of static images

Topic 8: Applications of image processing

Topic 9: Basics of digital video



LABORATORY:

- Design of discrete filters

- DPCM coder

- Edition and processing SW

- Real time processing

- Image processing

Theory: explanation of the fundamental concepts in the three blocks, and resolution of exercises and problemas corresponding to block 1.



Laboratory: individual or collaborative resolution of problems using Matlab; understanding the fundamentals of sound editors; real-time processing of audio signals (using DSP or GNU radio SW). Collaborative work and capacity of analysis and synthesis are promoted in the lab sessions.



In the event that the sanitary conditions prevent the realization ofa face-to-face teaching activity and/or evaluation, a non-face-to-face modality will be activated of which the students will be informed promptly.

The evaluation is a combination of the following:

Continuous evaluation:

- Written exam corresponding to the theory of PART 1 and PART2.

- Evaluation of the Laboratory Sessions corresponding to PART 1, PART 2, and PART 3.



Final exam:

- Written exam corresponding to the theory of PART 3.

- Written exam of the theory of PART1 and/or PART 2 in case the student did not achieve the minimum grade required for each part in the continuous evaluation (4/10). The grade(s) of the final exam will withdraw the previous grade(s).



For those who do not pass the minimum grade in the partial exams of the theory part in any of the first two blocks (4/10), there will be a new exam of the failed block(s). The grade of this will replace the grade obtained in the previous partial exam.



The final grade will be determined by the following criteria:

- The average of each block will be obtained with a weight of 65% assigned to the part of Magistrales and 35% to the part of

Laboratory Practices.

- The three blocks weigh the same in the final grade.

- It is necessary to obtain a minimum grade of 4/10 in the theory part of each block.

- It is necessary to obtain a minimum average of 5/10 in the total grade corresponding to the theory part.

- It is necessary to obtain a minimum average of 5 in the total grade corresponding to the Laboratory Sessions.

- To pass the course the minimum overall grade must be 5/10.



Once the Laboratory Sessions have been passed, the grade will be kept for subsequent exams.



Attendance to the Laboratory Sessions and the laboratory assignments are compulsory to pass the course.



Impossibility to carry out the mixed evaluation:



Students who waive participation in the mixed evaluation, will be able to accredit the achievement of the learning results of the subject through through a final evaluation that will consist of:



- Final written exam of the part corresponding to the theory clases, 65% of the grade.

- Laboratory test, 35% of the grade.



Students may waive the continuous evaluation up to the 13th week of the course, communicating it in writing to the teaching team of the course.
