Applied Electronics and Measurement
1st degree and Bachelor-level of the Bologna process in Computer Engineering - Torino
This course completes the basic electronic elements addressed in the previous "Electronic systems technologies' course, providing detailed analysis of medium-complexity electronic systems, including analog and digital units, and introducing some design issue. The course includes the fundamental concepts of Electronic Measurements, with reference to the measurement methods and instrumentation, with information on sensors and their interfacing.

Assessment and grading criteria
The final exam includes a written test and, on specific request, an oral discussion.
The written test includes
- 10 closed-answer questions
- 2 textual answer questions
- 3 numeric exercises
The time assigned for the solution is 2 hours, and the maximum mark which can be achieved with the written test is 27.
The final grade is a weighted average of the scores of written test and oral discussion (weight about 0.8) and lab reports (weight about 0.2). It is possible to take a supplementary oral discussion (duration 15'-20'), addressing all the topics covered in lectures and laboratories, and get additional points with reports on specific topics, or preparing lecture notes to be reused in subsequent years. Detailed rules for reports and notes are given during the first lesson.
