- In transmission and reception systems and in the main aspects of a superheterodyne receiver.
Subject name Telecommunications Laboratory
ECTS credits 4
Term Annual
Degree Programme/s Degree in Telecommunications Systems Engineering
Subject code/s as GC004
The subject of Digital Communications Laboratory is a practical course that instructs students to learn and become familiar with the elements and electronic systems involved in digital communications. Thus, the subject manages to be a link between the subjects of the telecommunications specialty and also reinforces and extends the theoretical knowledge acquired in this and other subjects in a practical way. The subject of Digital Communications Laboratory focuses specifically on the following areas: - Optical Communication Systems. - Simulation of RF systems. - Radio Systems - Systems of radio frequency and microwave - Digital modulations - Mobile communications ? Antennas.
Learning Outcomes of this subject are:
RA.1 Mastery of the use of instrumentation and measurement procedures in the field of telecommunications. Justification and correct interpretation of the results obtained.
RA.2 Know and parameterize components, circuits and subsystems commonly used in telecommunications.

The methodology is exposed below:
A. Theoretical and practical tables.
The course currently consists of 10 tables, 1 out every two weeks. In each of these tables one or more content items mentioned above are developed, so that the course objectives are achieved.
Students are divided into 10 groups. Every 2 weeks, each group is required to finish the table and rotated to the next table. Each group must be composed for 2 people.
Each table is self-contained and it is intended that each group works autonomously. Students must understand the theory, draw conclusions and know the basic operation of the equipment. The student has a teacher to answer questions and to guide him.
Each table includes not only the material necessary for the implementation of practices, but also with extra material so that students can experiment by themselves, going further and being able to delve deeper into the subject.
B. Virtual classroom and Forums.
Supplementary material is available for the tables. This allows a greater depth at some interesting topics for students, in addition to allowing them to discuss and collaborate with each other.
The course is assessed via oral examinations (highly significant activity):
A. A review is performed at the end of each table (which only a maximum number of students may apply). If the student passes the review, the table is released and no longer enters in the final exam. Also, the note mark obtained weights its corresponding % of the final semester note mark. If the table is not passed, the note mark does not affect the final semester note mark, but if a student fails two tables cannot apply for another review for the rest of the semester.
B. Two final exams (each a the end of each semester). The first, in December, assesses the first 5 tables. The second, in May, evaluates the remaining tables. If a table is released during the term, however, this no longer enters in the final exam. In the retake exam, students can do the exam of those semesters that were failed.
In these examinations, students must prove that they know the theory of the tables and that dominate the equipment operation, in front of to the questions/situations proposed by the teacher.
The final grade is calculated by weighting the released tables by 20% each (if any), and the final exam with the remainder (which will decrease the more tables the student has released).
Below are listed the objectives to pass the course:
Objective 1: basic knowledge of the subject.
Theory of operation and characteristics of the devices that are part of a digital communications system. The theory and characteristics associated to each system under study and each measurement being performed must be known.
Objective 2. Ability to apply the knowledge in a practical way.
The theory must be understood in order to be able to put it into practice, understanding the steps that take place and be able to evaluate the correctness and goodness of them.
Objective 3. Oral and written communication in their own language.
Students must be able to express clearly and precisely their knowledge. Moreover, the speed and correctness of the answers to the questions arisen by the teacher will be also evaluated.
Objective 4. Ability to work independently.
Practices are performed autonomously. Students must be able to understand their content.
The course has a book that covers all the subject.
