Upon successful completion of this course students will be able to:

- List and describe the basic components of a communication system and interpret its fundamental parameters.

- Operate formally with the usual stochastic processes in communication systems and analyze their spectral characteristics.

-Describe formally the basic techniques to modulate information in digital form.

- Identify the basic types of digital and analog modulations and be able to interpret the associated graphical representations (power spectral density, IQ constellation, eye diagram).

- Design an optimal receiver for basic digital modulation techniques based on elementary specifications.

- Program with computer tools oriented to the analysis, design and implementation of the modulation and demodulation subsystems from the point of view of the detection and generation of the signals.

- Manage instrumentation for the generation and detection of digital and analog modulated signals.

If the health conditions do not allow a presential teaching and evaluation, a non-presential mode will be activated and the students will be informed from time to time.

Two assessment systems are considered in ordinary call: on the one hand, the continuous evaluation system, which requires regular attendance at the classes and a regular follow-up of the subject, surpassing the partial exams that are carried out; on the other hand, the final evaluation system, basically consisting of a single final exam of the subject. Both systems are exclusive, so the student must expressly waive the continuous evaluation to be able to take the final evaluation test.



A) CONTINUOUS EVALUATION SYSTEM

A continuous evaluation will be carried out throughout the course through three individual partial evaluation tests (PEP) along with the evaluation of work done in the Seminars. In each of the PEP they will evaluate the competences acquired in solving problems (lectures, classroom practices and seminars) and in laboratories (laboratory classes):

- PEP1:

* Lessons 1 and 2 (PEP1-M)

*Laboratory Practice 1 (PEP1-L)

- PEP2:

* Lessons 3 and 4 (PEP2-M)

* Laboratory practice 2 (PEP2-L)

- PEP3:

* Lessons 5, 6 and 7 (PEP3-M)

* Laboratory Practice 3 (PEP3-L)



- Seminars: Teamwork evaluation: oral and written presentation of complex problems during the seminar sessions.

- A questionnaire will be performed in each laboratory session, with questions about the work to be done during non-presential teaching.

CALCULATION OF THE FINAL NOTE

------------------------

The final grade of the subject will be calculated with the following formula:



NF= 0,65*(N(PEP1-M)*0,3+ N(PEP2-M)*0,3+ N(PEP3-M)*0,4)+

0,25*(N(PEP1-L)*0,25+ N(PEP2-L)*0,35+ N(PEP3-L)*0,40)+

0,1*N(Seminars)

To pass the subject it will be necessary to fulfill the following conditions:

- Obtain an NF equal to or greater than 5 points out of 10 (5/10).

- Having obtained an average score in the part of Classroom (M) higher than 3 points out of 10, an average score in the part of Laboratories higher than 3 points out of 10, and an average score in the part of Seminars greater than 3 points out of 10. That is to say:

* N(PEP1-M)*0,3+ N(PEP2-M)*0,3+ N(PEP3-M)*0,4 must be equal or greater than 3 out of 10

* N(PEP1-L)*0,25+ N(PEP2-L)*0,35+ N(PEP3-L)*0,40 must be equal or greater than 3 out of 10

* N(Seminars) must be equal or greater than 3 out of 10



- Have a minimum attendance of 75% to face-to-face classes of laboratory and seminars.

- The questionnaires performed in each laboratory session will have to be passed.

In case you have not obtained a minimum of 3 points out of 10 in any of the sections and the final grade obtained through the formula was greater than 4.5 the final grade that will be reflected in the minutes will be 4.5 / 10.



ASSISTANCE TO THE PRESENTIAL TEACHING

-----------------------------------

To be able to follow the continuous evaluation system, a minimum attendance of 75% is required for face-to-face classes classes of laboratory and seminars.

This criterion will be applied throughout the course, so that in order to be evaluated in the partial evaluation tests (PEPs), this requirement must be met on the date of completion of each test.

The rejection of the continuous evaluation must be made through written communication to the teacher of the subject until April 30. The rejection of the continuous evaluation supposes the loss of the results of the evaluations previously carried out. The rejection of the continuous evaluation can be done separately for the laboratories, on the one hand, and for the set of classroom lectures -seminars, on the other. If the continuous assessment of the part of classroom lectures is waived, the seminars will automatically be renounced and the part of classroom lectures will have a weight of 75% of the grade.

B) FINAL EVALUATION SYSTEM

It will consist in the realization of an exam on the day of the ordinary call. The exam will have two parts, one written test consisting of problem solving of the subject and a test of laboratory practices.

The Final Note will be calculated by applying the following formula:

NF = 0.75 * N (M + PA) + 0.25 * N (Lab)

It will be necessary to obtain a minimum score of 3 out of 10 in each of the sections. That is to say:

- N (M + PA) must be equal to or greater than 3 points out of 10

- N (Lab) must be equal to or greater than 3 points out of 10

In case you have not obtained a minimum of 3 points out of 10 in any of the sections and the final grade obtained by the formula was higher than 4.5 the final grade that will be reflected in the minutes will be 4.5 / 10.

If you do not assist to the exam in the ordinary call, the rejection of it will be assumed in any case.
