PRACTICAL BLOCK

The practical block of the subject is made up of practices in the laboratory, and its nature is compulsory.

The objective of the proposed practices is to achieve the established competences, facilitating the student's understanding of the concepts included in the theoretical block of the subject through their practical study and through their association with basic engineering problems that serve as motivation.

In addition, information communication skills, ideas, problems and solutions in the field of engineering and society in general will be developed through documentation delivery processes or oral presentations.

With regard to the organization of work, collaboration and teamwork will be encouraged through the actual design of the practices.

The work is structured in two blocks:

Block 1. Signals and systems in the temporal domain.

Basic representation, classification, analysis and basic operations with signals and systems in the temporal domain. Application in engineering problem. It integrates practices 1 and 2.

Block 2. Signals and systems in the frequency domain. Sampling and filtering.

Basic representation of signals in the frequency domain from signals in the time domain. Study of properties of the Fourier transform. Filtering and sampling. Application in engineering problems. It integrates practice 3.

SEMINARS

In order to support the student, it is proposed to carry out a seminar to reinforce basic mathematical concepts in communications, which will be necessary to understand for the proper development of learning in the subject.

Seminar. Basic mathematical concepts in communications.

The development of the expository classes in large groups, as well as in small groups, will be focused on promoting quality teaching, prioritizing activities that promote inclusive and equitable learning (ODS-4).

A-1 Expository classes in a large group

The methodology to be followed in the large group lectures will be a mixture of introductory activities, master classes and the presentation of theory and general examples in the classroom designated for the subject by the center. In addition to exposing the theoretical contents of the subject, the ability to collect and interpret data and handle complex concepts within telecomunications/telematics engineering will be developed and enhanced, in order to make judgments that imply reflection on ethical and social issues.

The student must follow the teacher's presentation with the material delivered for this purpose, whether they are notes or slide presentations, which must be completed with their own notes and with the subsequent revision of the basic and/or recommended bibliography.

Active, respectful and responsible participation, whether to raise questions or to respond to the teacher's requirements or questions, will be positively evaluated in its corresponding factor. Likewise, the student's ability to make judgments about the concepts that are presented to them will be encouraged and valued positively, being especially important their ability to collect and interpret data and manage complex concepts within their specialty, to make judgments that imply reflection on ethical and social issues. In this sense, the ability to keep up to date with new developments in science and technology and to correlate these new developments with the content of the subject will be promoted in classes.

The student's autonomous work should focus on reviewing the concepts and theoretical aspects seen in class, carrying out exercises, as well as studying them with the material provided by the teacher, student notes and bibliography.

In addition, in the expository class sessions, controls will be carried out to supervise the progression and assimilation of the concepts by the student.

A-2 Small group classes

The work of the small group classes will be based firstly on practical activities in the laboratory. The student's work will focus on the development of applications, or learning tasks designated by the teacher, culminating in the achievement of the objectives set for practice. Secondly, the small group classes will consist of solving exercises and practical questions of the subject. Finally, seminars will also be held to delve into relevant and complementary aspects of the subject.

Attendance, as well as active, respectful and responsible participation, whether to ask questions or to respond to the teacher's requirements or questions, will be positively evaluated in its corresponding factor. In addition, communication and teamwork will be encouraged both in the exercise resolution sessions and in laboratory practices, and the ability to effectively communicate information, ideas, problems and solutions in the field of engineering and with society in general will be valued. .

With regard to autonomous work, it will focus on completing the work started in the laboratory and solving problems that could not be completed in the corresponding session. The ability to manage, in an introductory way, complex technical or professional activities or projects in the field of signal theory will be fostered, with the student taking responsibility for decision-making at various stages of their learning. With these activities, continuous training for students will also be promoted and the ability to recognize the need for their own continuous training and to undertake this activity throughout their professional life independently will be instilled.

In addition, work in a collaborative environment will be encouraged, as well as mixing with the communication of results, with special emphasis on the need for ongoing training in activities related to telecommunications throughout their professional life independently.

A-3 Collective tutorials

The collective tutorials will be used in the resolution of doubts, monitoring and supervision of the works and exercises in a virtual way through forums or other digital means indicated by the teaching staff as well as in the attendance and participation in different seminars, talks, conferences, workshops and/or or conferences, designated by the teacher, in order to complete and update the training and obtain general, transversal and/or specific skills defined for this activity, such as the value of continuous training, entrepreneurship or the review of technological innovations in the subject.

Attendance in the case of face-to-face activity, as well as active, respectful and responsible participation in the aforementioned activities, will be evaluated according to the provisions of the evaluation system of this guide.

Students with special educational needs should contact the Student Attention Service (Servicio de Atención y Ayudas al Estudiante) in order to receive the appropriate academic support

GLOBAL ASSESSMENT

The Global Assessment modality will be carried out according to the outcomes of the activities described in the section "Methodology and activities", in addition to those described in the section "Detailed description of the Global Assessment" that will be weighted by considering the aspects and percentages detailed in the above table.

The Global assessment modality consists of two parts:

• The work assessment during the term, according to the tasks defined for this purpose. 
• The completion of a FINAL EXAM on the day set for the exam during the evaluation period. 

The distribution of the weights for each assessable aspect of the two aforementioned parts, and according to the activities described in the table above, is as follows:

Table 1. Weighting of the Global Assessment.

Grades obtained in an aspect during the teaching term in the GLOBAL assessment will be maintained until the end of the academic year.

Final Exam: At the end of the term, on the day set for the course within the exam period, there will be a final exam of the theoretical part and exercises of the course (aspects S2 and S3), in which students must demonstrate that they have acquired the competences and learning outcomes established for these aspects. The weight of this exam in the final grade will be 30% of the total, as reflected in the table "Weighting of the Global Assessment", with 15% corresponding to aspect S2 and the other 15% to aspect S3. The specific conditions, as well as the material and/or documentation that may be used in the final exam will be established by the lecturer.

Final Assessment

In order to pass the course, students must obtain a grade equal to or higher than 5.0 out of 10 in the overall results considering all the assessed aspects, provided that they have obtained a grade equal to or higher than 4.0 in the final exam and in the laboratory/computer practical part (S4).

Students will have the option of resigning the GLOBAL evaluation, and it will not be possible to return to it once the resignation has been made.

FINAL EXAM

In the FINAL EXAM modality, an exam will be held on the day set for the course within the exam period, which will cover all the course contents, ensuring that students have acquired the competences and learning outcomes established for the course. The two parts of this written exam are weighed as follows:

• Part 1: Attendance and participation, theoretical concepts and completion of study cases or exercises assignments (S1, S2, and S3): 70%.
• Part 2: Laboratory/ computer practical work (S4): 30%.

The specific conditions, as well as the material and/or documentation that may be used in the Final Exam will be established by the lecturer.

In order to pass the course, students must obtain a grade equal to or higher than 5.0 out of 10 in each of the two parts.

Students who have passed the S4 aspect (laboratory/computer practical work) of the course, through GLOBAL ASSESMENT, with a grade equal to or higher than 5.0 out of 10, will not have to take Part 2 corresponding to this aspect in the exam. The same grade obtained in the GLOBAL ASSESTMENT will be assigned to this part.

The parts passed at each exam attempt will be maintained until the end of the academic year.
