Signal Acquisition and Processing (3 ECTS)

Overview

Description:
The central theme of this course is the message—its generation, transmission, reception (detection), and processing. Primarily through project-based lab sessions, 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 orient oneself in the realms of time and frequency,
  • 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.
