Electronics
Objectives
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
As aulas práticas e teórico-práticas serão leccionadas no regime online.
Apenas os exames serão presenciais.
No entanto os alunos deverão inscrever-se nos turnos práticos cumprindo todas as regras que era habitual existirem, nomeadamente o limite de alunos por turmas, etc.
Os alunos não poderão frequentar as aulas práticas se não estiverem nelas inscritos.
As aulas práticas, apesar de serem dadas em regime online, serão de presença controlada. A ideia é aproximar o regime online o mais possível do regime presencial.
Para tornar o ensino online eficiente e produtivo apelo aos alunos para se munirem dos meios necessários para as aulas de videoconferência, que devem incluir uma web câmara, pois nas aulas práticas vai ser necessário fazer controle de presenças através de uma identificação.
Theoretical classes, Laboratory classes where students implement and set-up electronic circuits with report, homework assignments, Final Project with reports. Problem solution classes every other week.
An emphasis is put on the applications and practical aspects 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)
test nº1:; 45%
test nº2: 45%
Threshold (0.1*teste1+.45*teste2+.45*teste3)>=9.5
or
(0.5*teste1+0.5*teste2)>=9.5
B- Three Labs 60%
Lab 1 (20%):
Lab 2 (20%):
Lab 3 (20%):
Final Project: 40%
Acess condition: Average in Lab1. Lab2, Lab3 and Final Project >=9.5
Final Project mark above 9.5
