Electronics for Measurement Systems - 4PMBEMS6

Goal(s)

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 input of the analog to digital converter.
