**5.1. Methodological overview**

#### The teaching/learning process is structured as follows:

1- Classroom lectures, in which the theoretical foundations of the subject are presented and where the student participation is encouraged. Multimedia and other bibliographic material can be accessed previously by the students on the official University digital repository.

2- Problem solving sessions, where the students show in the blackboard to their fellow colleagues how they have worked out exercises proposed by the teacher, individually or in small groups.

3- Laboratory sessions, with two separated relevant work packages. First, on the laboratory facilities, the students, organized in couples, will perform sets of experiments with test and measurement equipment and/or computer simulation software. Afterwards, they will produce a written report on a standardized format where they should present their data sets, analyze the results, compare them with theoretical models and draw the pertinent conclusions. A due date for each report will be fixed.

4- Small project work. The students will be organized in groups of four. Each group will have a proposed problem to work in. They should seek information to write a short paper with the relevant theoretical background needed to solve a specific problem. These very same theoretical foundations will be the basis to understand and explain the experimental results of a specific test that themselves will accomplish in the laboratory. A report with the data and its interpretation has to be produced, too.

5- Individualized tutoring by appointment in given dates

6- Assessment and evaluation exams

7- Student homework

**5.2. Learning tasks**

**The program offered to the students to accomplish the desired learning objectives is organized in the following activities:**

**- Classroom lectures (active student participation is encouraged) **(40 hours). Designed to gradually advance in the learning outcomes R1-R2-R3-R4 and R8

**- Problem solving sessions** (10 hours). Designed to gradually advance in the learning outcomes R1-R2-R3-R4-R5-R6 and R8. To take place in the classroom

**- Laboratory sessions** (10 hours) Five mandatory sessions of two hours each in which the students will work in couples. To take place on the teaching laboratories of the Department of Electronic Engineering and Communications (Ada Byron building), oriented towards learning result R7.

**- Small Project work in group ** (14 hours). This mandatory activity is oriented to advance in all the proposed learning outcomes. Part of it will take place on the teaching laboratories of the Department of Electronic Engineering and Communications (Ada Byron building)
