Teaching methods
Lectures.
Exercises are solved in the classroom and deal with the analysis and design of simple analogue circuits.
Assessment methods and criteria
Final written test and oral exam
A positive result in the written test is mandatory to access to the oral exam, which is based on simulator.
For a final grade higher than 26/30, the student must ask for an optional part of the oral test, based on theoretical questions.
Books or manuscripts cannot be used during the written test.
If a positive result is achieved in the written test, oral exam must be taken within the same session
If the oral exam is not passed, the student must repeat the written test.
The final mark is the weighted average of the marks achieved in the oral exam and written test.
To access to the written test, subscription at the dedicated www pages (at www.unipr.it) is mandatory.
