Laboratório de Instrumentação e Aquisição de Dados

Objectives

The Curricular Unit aims at giving the students the knowledge on the techniques used in intrumentation and data acquisition and the application of these concepts in the development of a project. The project development can be linked to ongoing research activities.

Syllabus

Basic Instrumentation. Cables and Connectors, power supplies, multimeters and oscilloscopes, DC and AC coupling, triggering, YT vs XY modes, waveform generation (sinusoidal, square, triangular) Signal conditioning. Filters, impedance, voltage regulators, Operational Amplifiers, buffers, summing, differentiation and integration, instrumentation amplifiers Signal acquisition. Analog i/o (ADC and DAC resolution and speed), signal processing, parameter identification and estimation, ADCs and DACs Digital Electronics. Gates, counters and oscillators, devices, implementation, FPGAs and their programming. Computer Basics, computer i/o, serial ports, audio i/o Experimental Techniques. Step response and square wave testing, sinusoidal testing and swept sine testing Fast and high sensitivity detectors. High channel density. ASICs. Feedback systems at high frequency.

Prerequisites

The students should have a basic knowledge of electronics and instrumentation

Cross Competence Component

80% - Critical and innovative thought 20% among intrapersonnal Competence, interpersonnal Competence and Information Literacy.

Laboratorial Component

The CU has a strong laboratory component which is directly linked to the project development. The tutorial sessions will guide the development of the project. Students are supposed to be autonomous in the laboratory.

Programming And Computing Component

Part of the project will require the development of programs to use the computer to get data. Some preliminary treatment of data may be also part of the course if necessary to test the developed system.

Ethical Principles

All members of a group are responsible for the group’s work In any assessment, every student shall honestly disclose any help received and sources used. In an oral assessment, every student shall be able to present and answer questions about the entire assignment and solution.
