Teaching methods
Classroom lectures and exercises solved by the instructor and by
students.
Assessment methods and criteria
Written exam. There is a single exam for the two modules making up the integrated course.
As far as Applicazioni Industriali Elettriche students will have to demonstrate knowledge of the techniques for the time analysis and synthesis of electric systems including energy behavior.
It is considered important the capability to solve simple quantitative exercises by hand calculation. As far as Elementi di Elettronica, students will have to demonstrate knowledge of the techniques for the frequency-domain analysis of linear systems treated in
the lectures, and the ability to apply them. They are also expected to be able to analyze the behavior of simple circuits. It is considered important that students be able to solve simple quantitative exercises by hand calculation.
The final vote is calculated by assigning a mark in the range 0-30 for each part of the course and then performing the weighted average of the individual evaluations, with final ceiling to the next unit; the test is exceeded if it reaches a score of at least 18 points. “30 cum laude” is given to students who achieve the highest score on each item and use precise vocabulary.
