Teaching language

Suitable for English-speaking students

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.

Teaching methods and learning activities

This is a practical course, with an active teaching methodology. Laboratory equipment is used during the lectures and practical sessions, as well as computing systems for e-learning and computer algebra system (CAS).

The practical sessions are conducted in the Department of Engineering Physics's computer room (room B233). During those sessions students work in groups of two at one of the computers in the room, which has access to the support material including some practical activities or simulations, lecture notes, multiple-choice questions and proposed problems. Students should answer the multiple-choice questions among and solve some of the problems in the chapter for that week. The remaining problems in the chapter are left as homework.

The master classes are used for conducting experimental demonstrations, as well as giving further explanations for the material on the textbook. The support for this course, including lecture notes, teaching materials, quizzes results, and communication among students and teachers, is done using the e-learning server (https://def.fe.up.pt/eic0014) which has public access, except for the sections related to evaluation.

Eligibility for exams

Calculation formula of final grade

If D denotes the grade for the distributed component and E the exam grade, the final grade is calculated with the following equation:

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

Namely, if the grade of the distributed component is higher than the exam grade, the distributed component will have a weight of 40% and the exam 60%. But if the exam grade is higher, the distributed component will be ignored and the final grade will be the exam grade. There is no minimum grade required in the exam and the exam grade will have one decimal digit. 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, ...)

Students who are not required to attend classes and obtain a grade for the distributed component do not need to make any additional tests or assignments before the exam. The final grade will be equal to the exam grade rounded to an integer.

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").

Observations

It is recommended a period of off-class independent work of at least 3 hours per week, in order to keep off with the subjects introduced every week. Independently of their attendance status, it is expected from all enrolled students to preview at home the chapter of the textbook which will be covered in the following practical session. The physical concepts covered in this course can only be fully grasped by reflecting on them during the whole semester. It is also recommended to periodically check the announcements and forum messages posted in the e-learning server.
