Introduction to Electronics

Objectives

This course is aimed at explaining the basic operation of electronic components such as transistors and diodes in simple simple electric circuits. It is intended that students learn the electrical characteristics of these components as well as learn the sizing of simple electronic circuits. The study of operational amplifiers and circuits with operational amplifiers, is also considered.

The student will develop the ability to solve problems, work in a team and autonomously. The student also learns to improve their ability to manage time available. Attention is given to the ability of written and oral presentation of the work performed.

Teaching method

The theoretical concepts of the course syllabus are explained in the theoretical-practical classes and then the application of these concepts is clarified through exercises and practical examples of circuits.

Resolution of sets of problems, available in the web page of the course, before the classes. Laboratorial classes with preparation in advance and report done by the students. Final project.

Continuous assessment in practical classes, laboratory work with writing report, three tests or final exam.

Evaluation method

Final grade (FG) is computed by:

FG = 0.6*T + 0.4*P
