Signal Acquisition and Processing (3 ECTS)

Overview

Description:
The central theme of this course is the signal: its generation, transmission, reception (detection), and processing. Through a series of practical sessions conducted primarily as projects, the course covers the concepts of analog and digital signals and the instrumentation chain.

Objectives:

• Be able to understand the concepts of signals and messages,
• To be able to navigate through time and frequency spaces,
• Be able to master the basics of signal processing,
• Understanding analog-to-digital conversion and vice versa,
• Understanding programming:
  • algorithm development,
  • mini-project management,
  • Understanding sensor/actuator interfacing using LabVIEW.
