SCRITTO E ORALE CONGIUNTI
Basic electronics from the courses of Electrotechnics or Electromagnetic Fields and Circuits I
The course is meant to provide an overview on electronics for application to industrial measurements. At the end of the course, the student is supposed to be able to: 1) recognize the most simple and popular amplification and filtering schemes and understand their operation; 2) analyze analog circuits based on operational amplifiers and combinatorial digital networks; 3) choose the values of component parameters based on the requirements of a specific application; 4) use an appropriate language in describing simple analog and digital circuits and their operation. The course also aims at providing students with the possibly needed tools to expand their knowledge of electronics beyond the course program.

Lectures (hours/year in lecture theatre): 38
Practical class (hours/year in lecture theatre): 6
Practicals / Workshops (hours/year in lecture theatre): 12
Classroom lectures are given at the blackboard and are completed with practical classes, consisting of solving tests from previous years of the course.
Workshop activities are carried out in the electronics teaching lab (laboratorio didattico di elettronica, room B3) and consist of the design and implementation of systems for acquiring signals from transducers. Experience execution also involves using the bench top instrumentation available in the lab.

Modalità verifica apprendimento
1) Written exam.
Closed-book, closed-notes, 2 hour and 30 minute written exam consisting of 4 to 6 sections assessing the student’s knowledge and understanding of the course topics and problem solving capabilities. Threshold to pass the exam is 18/30, maximum mark is 30/30 cum laude. The final mark for the written exam will result from the weighted average of the marks obtained in each section of the written exam.
2) Oral exam.
Typical duration is 1/2 hour, including the revision of the written exam and 1-2 questions. The exam will assess the student’s knowledge and understanding of the course topics, problem solving capabilities and technical communication skills. Threshold to pass the exam is 18/30, maximum mark is 30/30 cum laude. The final mark for the oral exam will result from the weighted average of the marks obtained for each question of the oral exam.
The final mark for the overall exam will result from the weighted average of the written exam (70%) and the oral exam (30%) marks. Threshold to pass the exam is 18/30, maximum mark is 30/30 cum laude.
