Objectives

Nowadays information processing, storage and transmission are done using electromagnetic phenomena. Therefore, the background knowledge for a computer engineer must include the study of electricity, magnetism and electric circuits.

This course aims to provide the students with basic knowledge on electromagnetism and signal processing. An experimental approach is used with simple on-hands experiments that the students may conduct during the practical sessions, in order to strengthen the subjects covered in the lectures and to gain experience with the use of measuring devices. The Computer Algebra System (CAS) used in Physics 1 is also used in this course to help solve problems and to visualize electric and magnetic fields.

Learning outcomes and competences

In order to pass this course students must prove to be able to:

• Analyze simple electrical circuits explaining their working principles.
• Identify electromagnetic phenomena in their daily experience.
• Use physical principles to explain how electric appliances work.
• Evaluate different electrical devices which perform the same task (for instance, displays based on CRT, plasma, LCD, OLED, etc) pointing out their pros and cons.

Working method

Presencial

Pre-requirements (prior knowledge) and co-requirements (common knowledge)

Enrolled students are expected to have background knowledge in mechanics: velocity, acceleration, force, Newton's laws, work and energy, and in math: geometry, algebra, trigonometry, linear algebra, functions, derivatives, antiderivatives and integrals.

Teaching methods and learning activities

The theoretical lectures are master classes including some experimental demonstrations. The practical sessions are dedicated to the resolution of problems and theoretical questions.

Eligibility for exams

In order to be admitted to the exams, enrolled students must attend at least 75% of the practical sessions and take a quiz obtaining a grade of 5 or more. Students who don't fulfill those two requirements will fail the course with a grade of RFF (failed for lack of attendance) when the first condition is not met, or RFC (failed for lack of a requirement) if the minimum grade was not obtained in the quiz.

Students who were registered in the course in the previous year ending with a grade RFF will have to fulfill the two conditions described above. If the grade was RFC, they don't have to attend the practical sessions but will have to take the quiz and obtain the minimum grade. If the final grade was different from RFF or RFC, there are not requirements to do the exam, but they may take the quiz to try to improve that part of the grade.

Calculation formula of final grade

If Q denotes the grade on the quiz and E the grade on the exam, the final grade is obtained from the following expression:

Maximum ( E; 0.4*Q + 0.6*E )

Namely, if the quiz grade is higher than the exam grade, the quiz has weight of 40% and the exam 60%. But if the exam grade is higher, the quiz is ignored and the final grade will is the exam grade. The exam grade is rounded to one decimal digit and there is no minimum grade requirement. The final grade will be rounded to an integer (9.5 is rounded to 10 but 9.4999 is rounded to 9).

Examinations or Special Assignments

None.

Special assessment (TE, DA, ...)

The special exam has a different format from the two other exams; the quiz is not considered and the final grade is the grade obtained in that exam. Working students do not have any requirements to do the exams and their final grade is also the equal to the grade obtained in the exam. Students who have valid reasons for not attending 75% of the practical sessions are treated as working students.

A student who in the previous year has been exempted from the conditions to be admitted to the exams for being a working student, might be subjected to those conditions these year if that working-student status is no longer valid.

Classification improvement

Students can attempt to improve the grade obtained in an exam, only once, up to the remedial exam of the following year in which the course was passed. The final grade to the course is the highest between that previously obtained and the one resulting from the new exam taken. The distributed-component grade can be improved in subsequent years by taking the two qizzes again (see the section "Distributed-component grade").
