Learning Outcomes

General objectives: Students should develop skills in terms of analysis, application, and evaluation of communication systems.
Essential Skills: At the end of this UC, students should have developed a set of skills related to the analysis and design of Telecommunications Systems. Special emphasis will be given to concepts, tools, and technical applications.
Soft Skills: Use technical-scientific notation/language correctly; Communicate properly in Portuguese and encourage interest in/use of the English language; Deepen knowledge in the areas of information technology and electronics; Promote the correct use of laboratory equipment.
