| Educational objectives |
Purpose of the course is:-a better understanding of theoretical subjects of Physics II course;-the knowledge of the methodology of performing a laboratory experiment;-a deeper understanding of problematics related to data and error analysis.The main competences (i.e. the ability of applying the acquired knowledge) will be:-the development of a general method to address whichever experiment, known or new;-the ability of dealing with experimental errors in a way both rigorous and flexible;-the skills for a proper behaviour in a scientific laboratory
|
| Prerequisites |
In order to understand and apply the majority of the techniques addressed in the course, it is necessary to have successfully passed the exam of Laboratory I.It is also useful to have attended to the Analisi Matematica I and Fisica II courses, and possibily have successufully passed the corresponding exams.

| Learning verification modality |
The exams consists of an oral discussion and possibly of an experimental test.The oral exam consists in an interview lasting about 20 to 30 minutes, during which the student discusses the written reports of the laboratory experiments performed in groups during the course, including the subjects of physics and statistics necessary to the execution of the experiments, with special attention payed to the experimental errors treatment. The interview aims at evaluating the understanding of the experimental techniques and metodologies and the capability of the student of applying them in different experimental situations.The practical part is optional at the discretion of the teacher, in case he finds out its necessity during the discussion of the oral part. The student has to personally perform a practical experiment similar to those conducted during the course, and concomitantly write a report on it. The duration of the experimental test is of about 3-4 hours. The goal of this practical test is to verify the experimental skills of the student, his knowledge of the experimental method and the ability of applying it to a new situation.

| Educational objectives |
The main objective of the course is to provide students the techniques to deal with the study of complex analog and digital systems with particular focus on: their performance in terms of cost, speed, power consumption, efficiency, resistance to noise and external disturbances; their design according to the solution of simple physical problems. Students will also be able to program simple logic systems or finite state machines in HDL language. |
| Prerequisites |
The contents of the Laboratory II - Mod. 1 are considered highly preparatory for the purpose of understanding and assimilating the topics covered in this course. In addition to this a basic preparation in the following topics is recommended: Discrete calculation (numerical series); Infinitesimal calculus (limits, derivation, integration); Classic electromagnetism; Basic electronics; Basic programming elements; Basic elements of statistics and data analysis techniques. |
| Teaching methods |
Front lessons for a theoretical introducion to the module and for preparation to the single experiments. Practical experiments in laboratory. Students will be organized in 2-4 people groups. Some experiments will be performed by every group, lasting few 5 hours sessions. |
| Other information |
Attendance of laboratory activities is mandatory for at least 70% of the total activities |
| Learning verification modality |
The exam includes an oral test aimed at ascertaining the level of knowledge and understanding reached by the student on the contents indicated in the program. At the beginning of the exam, students are expected to exhibit a technical paper produced independently or in a group by one of the practical experiences carried out in the laboratory. The skills of synthesis and autonomous organization of the exposure of the problem and of the applied methodologies will be evaluated, as well as the ability to contextualize the study of the proposed problem within the theoretical contents introduced in the lessons with appropriate language properties. |
