  • Number of hours

    • Lectures : 16.0
    • Tutorials : 12.0
    ECTS : 3.0

Goals

All electronic systems interacting with the real world include sensors and/or actuators.
This course is meant to provide an introduction to the analog electronic processing of the signal provided by a sensor. A complete system will be studied, from the sensor to the analog to digital converter.
