Learning outcomes This curricular unit aims to provide the basic concepts related to the data acquisition systems. Mainly, the main functions and characteristic of the elements that belong to the data acquisition systems, the main ways of transmitting signals and their different architectures.
At the end of this course the student should be able to:
• Describe the different architectures of data acquisition systems and know how to select the most appropriate architecture for each problem;
•Interpret and apply the specifications of the main elements that compose the data acquisition signal chain;
• Describe the most important techniques of AD and DA conversion
• Describe the architecture of data acquisition systems;
• Design and configure data acquisition system based on fieldbus networks: the CANopen case;
- Design data acquisition systems for specific applications;
- Ability to operate with the laboratorial instrumentation.

Teaching Methodologies and Assessment Criteria The Assessment is accomplished, with the adjusted weighting, of the theoretical knowledge assimilated by the student, his performance in laboratory activities, his bibliographic research activities and his commitment.
Assessment methods and criteria:
Final mark = {50%TESTE} +{40%LAB + 10%TI}
LAB > Laboratory activities
TI > Research work
TESTE> Exam or test mark.
It is necessary to obtain a minimum grade of 9,5 Val at LAB component be admitted to exam.
Language Portuguese. Tutorial support is available in English.
