Objectives

This course aims to introduce students to signal processing which need to be treated with digital electronics. There is a chain which is dedicated to analogue signal processing (amplitude adaptation, impedance adaptation, change of level DC, filtering, noise elimination, current/voltage conversion and vice-versa, compression, expansion, mathematical operations, multiplexing, etc…) and convert it to the digital world (ADCs, SHs, etc…). This course also aims to acquaint students with the classification of analogue signals, application operations, as well as error analysis and quantification, and A/D conversion. Learning Outcomes: At the end of the course students should be capable of: 1. Identify and apply methods for signal acquisition and processing . 2. Analise noise influence on the performance of an instrumentation system. 3. Identify and apply methods and sampling techniques in the domains of time and frequency. 4. Identify and apply methods and techniques for analogue filtering. 5. Project analogue to digital acquisition systems to the most common physical quantities (temperature, light, pressure, tension, force, pH, sound, distance, acceleration). 6. Identify and analyse interfaces between logic families (TTL/CMOS...). 7. Identify and analyse power amplifier stages.

Eligibility for exams

Students will only be admitted to the final exam (FE) if they attend to the practical classes, and if they achieve a minimum mark of 8 out of 20 in the laboratory component. They must obtain a minimum of 8 out of 20 in the final exam.

Calculation formula of final grade

Final Mark will be based on the following formula:

0.6*EF+0.4*TP

All components of the course will be assessed in a scale of 0 out of 20

EF: Final Exam.

TP: Practical Assignment (Laboratory).

TPC: Homework.

QAP: MOODLE quizzes.

Students have to reach a minimum mark of 8 out of 20 in the final exam and in the practical assignment, to complete the course.

Examinations or Special Assignments

Not applicable

Special assessment (TE, DA, ...)

Students with a special status (working-students, military personnel and students’ association leaders) have to attend a practical exam.

Classification improvement

According to Article 10 of General Evaluation Rules of FEUP.

Observations

Students’ knowledge that was acquired in other courses (Digital Systems, Circuits, Electronics, Introduction to Linear Signals and Systems, and Measurement, Sensors and Instrumentation) should be revised.

Office hours: Office hours will be scheduled with each group of students.
