Overall hours
Learning objectives
The learning objective of this course is to teach the student the most common experimental techniques through the analysis of tipical signal processing chains used in particle physics experiments. By the analysis of the signal transmission from the detector, to the "off-detector" readout electronics, the students will develop competences on the communication protocols and of the techniques for data transmission and processing.
Expected learning outcomes
After completing the course:
1) the student will be familiar with the signal processing chains starting from a particle detector.
2) he/she will be able to perform measurement of linearity and noise of the electronics chains and to optimize the signal shaping according to the experimental conditions
3) he/she will be ablw to perform and understand impedence and transfer function measurements.
4) he/she will develop competences in the offline analysis of the acquired signal
