Electronic Measurements Laboratory

The subject is expected to show a practical and pragmatic view of different topics related to electronic and communication systems, focusing on methods and procedures of measurements. Hence this is a very heterogeneous subject. The subject takes place in the Laboratory where 18 different practices can be found. Each of them has its own equipment to be carried out. The practices are carried out by couples, one per week. In order to get a high quality teaching environment the class is divided in groups, each one has three hours per week to be in the Laboratory. Two professors remain at the Laboratory to help the student go through each course.

The training activities that are used in the course are:

- Lab Work
- Individual practical lab work
- Individual study and project work
- Evaluations

The student must complete 18 practices through the whole course, each one of them is in a different table with all the required equipment. The practices are carried out in couples. A different practice is assigned to each couple every week.

From the beginning of the course students have a didactic handbook for each practice which has a brief explanation of the theoretical concepts, measurement procedure, hardware description and how to carry out each practice.

The student must understand the theoretical concepts and the proposal for each practice. Afterwards each couple has two hours at the laboratory to carry out the practice with the help of two professors. The laboratory remains open all a very long time in order to permit students to finish the practice and strengthen the knowledge and acquire experience. Professors are also open to answer whatever question the students may have.

As a teaching tool the e-campus is commonly used. The e-campus is a virtual environment which allows a fluent dialog between teachers and students in order to be able to exchange files, send e-mails and notices, forums can also take place in the e-campus, as well as many other issues.


Assessment activities:
- Exams
- Participation in the laboratory - Continuous assessment

Evaluation Criteria

The subject is divided in two terms; each of them is formed by 9 practices. The exam is oral and about 4 of the 9 practices. Each term´s grade is the average of the grade obtained in each practice. During the exam, students are allowed to have over the table the notes they consider necessary.

The final grade is made by the arithmetic mean of the two terms´ grades. To pass the subject, both exams must be passed with a note equal to or higher than 5. If the event of failing one of the exams, the student will has the possibility to take an exam on September (first week) that consists in oral questions about four practices. Therefore, partial saved approved by the extraordinary, but not for the next course.

We have designed a rubric for assessing oral examinations. It is evaluated by differentiating three aspects: knowledge and theoretical fundamentals, ability to apply the methods and procedures for the realization of the measures and oral expression and argumentation ability. The latter is not used to calculate grade, only to give guidance to students.

Continuous assessment consists of an oral examination. Weekly can release material by an oral exam practice done during the week.

Should have passed some practical continuous evaluation, the test is done on the rest. Wondering about approximately 50% of pending practice.

The grade of each part will be the average of the grades weighted number of practices of each test.

Example: If the partial examination is about nine practices, and have released 4 continuous assessment Notes 7, 8, 7 and 9, will be examined in the remaining five practices. The test might be to ask 3 of the 5 practices. If the note of this examination was 8, the final note of the part would be: 7x1 / 8x1 9 + / 9 + 7x1 / 9 + 9x1 / 9 + 8x5 / 9 = 7.86
