AIMS AND CONTENT LEARNING OUTCOMES Learning of experimental methods to analyze signals of time-varying physical systems using their representations in the time and frequency domains. AIMS AND LEARNING OUTCOMES At the end of the course, students will be able to design a data acquisition and processing system, using commercial components and being able to operate in both the time and frequency domains. Furthermore, they will have acquired a basic knowledge of the concepts of noise and disturbance and will be able, at least in the simplest cases, to correct problems that arise in a real experimental system. Students will also have a more in-depth knowledge, compared to the courses taken in previous years, of system control, studying their stability and the design of feedback mechanisms. The goal is to be able to study a system, predict its level of stability and act accordingly to improve its behaviour. PREREQUISITES "Laboratorio 2" course. TEACHING METHODS Lectures and group practical exercises in the laboratory, carried out during the course. SYLLABUS/CONTENT Complete characterization of time-invariant linear systems in the time and frequency domains; use of Fourier transforms. Study of of correlation, autocorrelation and cross-correlation techniques. Techniques for the extraction of the signal of interest with respect to noise and disturbances; understanding and using lock-in amplifiers. Introduction to control theory: differential and algebraic equations with the transition to Laplace transforms; study of the response and stability of the system, through the analysis of its transfer function (search and factorization of poles and zeros). Feedback design: introductory examples, techniques for modifying the transfer function of a system, application of stability criteria (root locus, Nyquist, Bode). Design of data acquisition software using LabVIEW and study of system response using MATLAB. Practical lessons in the laboratory, aimed at demonstrating in practice and at deepening the concepts studied in class. RECOMMENDED READING/BIBLIOGRAPHY Material available on AulaWeb (lecture slides and handouts). In addition: The Fast Fourier Transform and Its Applications E. O.

Delivery and subsequent evaluation of a report on the project carried out. Oral exam, accessible on condition that a positive evaluation of the report has been obtained. ASSESSMENT METHODS The oral exam largely focuses on the discussion of the project presented, with links to the theoretical aspects addressed during the course. In addition, other topics are addressed, to assess the overall theoretical knowledge of the student. This is meant to evaluate not only the knowledge of the topics covered during the lessons, but also the scientific communication skills and the ability to practically and autonomously apply the techniques acquired during the course.
