TEACHING MATERIALS AULAWEB

OVERVIEW

Laboratory course dedicated to data acquisition with advanced and modern 
instrumentation and data analysis with sophisticated computer systems.

 

 

AIMS AND CONTENT

LEARNING OUTCOMES

Acquisition of analytical and experimental methods for the analysis of 
time-varying physical system signals using their representations in the time 
and frequency domains.

 

 

AIMS AND LEARNING OUTCOMES

At the end of the course the student will be able to design an acquisition 
system using commercial components and to analyze the data obtained both in the 
time and frequency domain.
Furthermore, the student will have a basic knowledge of the concept of noise
and interference and will be able to calculate the instrumental limits and,
in the simplest cases, to correct any problems present into an experimental 
system.

The student will also have an introductory knowledge to the concept of feedback
and to the problem of stability. In the simplest cases it will be able to 
design a system, predict its stability or not and act accordingly to improve 
its functioning.

 

 

PREREQUISITES

TEACHING METHODS

Frontal lessons and practical group exercises in the laboratory during the 
course.

SYLLABUS/CONTENT

EXAMS

EXAM DESCRIPTION

Individual laboratory practical test or experimental thesis, then (if practical 
test or thesis are judged sufficient) oral exam to complete the test. 
The subject of the essay is agreed between teachers and interested students
and concerns topics of experimental physics.

The weight of the practical exercises on the final grade is 10%, the practical 
test 50%, the essay 40%, the rest of the weight of the vote is provided by the 
oral exam.

ASSESSMENT METHODS

The oral exam is always conducted by the responsible teacher and another expert 
and has a duration that varies between about 20 and 40 minutes. 
It is articulated on a fixed number of questions that focus on the exam program
and allows the commission to judge, in addition to the preparation, the degree
 of achievement of the communication objectives, autonomy, etc.

The thesis allows the verification of the achievement of the following 
objectives: practical use of the acquired knowledge, expertise on expressing 
and reporting obtained results, etc.
