Signal Acquisition and Processing (3 ECTS)

Presentation

Description :
The common thread of this course is the message, its generation, its transmission, its reception (detection) and its processing. Through mainly practical sessions carried out in the form of projects, the concepts of analog and digital signal and the instrumentation chain are addressed.

Objectives :

Being able to master the notions of signal and message,
Being able to find one's way in the spaces of times and frequencies,
Be able to master the basics of signal processing,
Understand analog/digital conversion and vice versa,
Understanding programming:
- development of algorithms,
- mini-project management,
- Understand the interfacing of sensors/actuators via Labview.
