LABORATORY:

Implementation of some laboratory practices which deal with the fundamentals of Analog and Digital Electronics. Equipment handling and application of some techniques to perform measurements on electronic circuits.

Learning Activities and Methodology:

- Theory - Lectures (large group), problem resolution ¿ Seminars (small groups), individual tutorials and student personal homework; oriented to theoretical knowledge acquisition.

- Laboratory practices oriented to practical knowledge related with the contents of the course.

- Computer aided sessions in small groups using CAD tools for electronics circuits¿ simulations. The aim of these sessions is to encourage the use of the CAD tools to complete the theoretical-practical learning during the course.

Assessment System:

The subject involves the following activities:
- Part 1 (theory/problems): Digital electronics, electronic circuits and instrumentation, and RC filters.
- Part 2 (theory/problems): Diodes, transistors, operational amplifiers and A/D and D/A converters.
- 4 lab sessions (laboratory).
- Lab practice Individual Exam.

The student must fulfill the below requirement to have the option to pass the subject:
- To obtain a minimum score of 3 out of 10 (3points/10points) on each part of the subject (Part 1 and Part 2).

The student must fulfill the below requirements to obtain a score related to his/her continuous assessment process:
- To do the Partial Exam of the subject (Part 1) that will be held during the semester.
- The attendance to the lab sessions is MANDATORY.
- To obtain a minimum score of 3 out of 10 (3points/10points) in the Lab Practice Individual Exam. This exam is MANDATORY.

The Final Exam has two differentiated parts (Part 1 and Part 2). The student will be exempt from being evaluated of Part 1 (theory/problems) within the Final Exam if his/her score on the Partial Exam was greater than or equal to 5 points/10 points.

ORDINARY EXAM
If the student fulfills the requirements to obtain a score related to his/her continuous assessment process, the final score will be obtained from:
35% Partial Exam.
- 15% Lab sessions.
- 10% Lab practice Individual Exam.
- 40% Final Exam.
---------------------
If the student failed to fulfill any of the requirements to obtain a continuous assessment score, the score (outside the continuous assessment process) will be obtained from:
- 15% Lab sessions.
- 10% Lab practice Individual Exam.
- 60% Final Exam.

RETAKE EXAM
The student that fulfills the requirements to obtain a score related to his/her continuous assessment process, maintains the same evaluation criteria than in ordinary exam, where the Final Exam refers to the retake exam.
-------------
If the student failed to fulfill any of the requirements to obtain a continuous assessment score, the score (outside the continuous assessment process) will be obtained only with the Final Exam (100%) from:

- 45% Part 1.
- 55% Part 2.
---------------
The student that fulfills the requirements to obtain a score related to his/her continuous assessment process, will be scored with the better of the two options above.
