    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.

    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 usually 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.
