Signal Acquisition and Processing (3 ECTS)

Presentation

Description:
The main theme of this course is the message, its generation, transmission, reception (detection) and processing. The course covers analog and digital signal concepts, as well as the instrumentation chain, mainly through hands-on projects.

Objectives :

• Master the concepts of signal and message,
• Be able to find your bearings in time and frequency spaces,
• Master the basics of signal processing,
• Understand analog/digital conversion and vice versa,
• Understanding programming :
  • algorithm development,
  • mini-project management,
  • Learn how to interface sensors/actuators via Labview.
