Students are introduced to the basic of Electronics.

Since some of the students did not have any exposition to Electric Circuits Theory, an introduction is required.

The prevalent idea is to prepare students for the subsequent disciplines in Electronics and Instrumentation, giving them a solid background in the basics of diodes, bipolar junction transistors  and field effect transistors. An introduction to Operational Amplifiers is also covered. Being a subject for Biomedical Engineering an emphasis is put on circuits involving bio-signals amplifiers.

Teaching method

Students must register for practical shifts complying with all the rules, namely the limit of students per class, etc.

Students will not be able to attend practical classes if they are not enrolled in them.

The practical classes will be indirectly controlled through random questions about the proposed exercises.

Theoretical-practical classes may include solving exercises. . Laboratory classes where students assemble electronic circuits. Final reports. Mini-Projects and Final Project.

Emphasis is placed on practical applications of electronic circuits.

Evaluation method

Some of the practical classes can be in thr DEE Lab

Final= 60% Tests+ 40% Lab

mini test ( test 1) : 10%  (The existence of this test will depend on the online teaching evolution)
