Bridging Courses

Although there are no mandatory prerequisites for this exam, students are strongly encouraged to take it after the exams of: Calculus, Discrete Structures and Linear Algebra.

Learning Achievements (Dublin Descriptors)

Knowledge and understanding:

At the end of the course the student will learn the fundaments of signal analysis, will know how signals can be processed using digital filters, will know the main digital filter structures and how these can be designed and she/he will acquire the ability to understand the principles and methods at the basis of any DSP system.

Applying knowledge and understanding:

The student will learn the methodologies of digital signal processing (DSP) and will be able to apply them for processing audio signals. In particular, she/he will be able to analyze signals, to process them using digital filters and to design different kinds of DSP filters.The ability to apply these techniques will be developed and sharpened in the laboratory exercitations, where audio signals will be analyzed.

Making judgements:

The student will be able to apply the methodologies of DSP for understanding and solving novel problems involving signal processing.

Communication skills:

The student will acquire the ability to communicate the fundamental concepts of DSP with an appropriate and rigorous terminology. She/he will learn to describe the problems related to signal processing and the methodologies adopted for their solution.

Learning skills:

The student will acquire the ability to study and learn novel techniques for signal analysis and signal processing, and she/he will be able to develop autonomously solutions for novel problems related to DSP.

Teaching, Attendance, Course Books and Assessment

Teaching

Frontal lessons and laboratory activities

Attendance

Although recommended, attendance of this course is not mandatory.

Course books

S. Mitra, "Digital signal processing", McGraw-Hill, 2001, 2011.
A. V. Hoppenheim e R. W. Schafer, "Discrete-time signal processing", Prentice Hall, 2010.

Assessment

Written exam and oral exam.

The written exam is evaluated in thirtieths and it is passed if the mark, which holds for the whole academic year, is at least 15/30. The oral exam, which is composed by open answer questions, can be performed only after passing the written exam and predominantly contributes to the final mark. The evalution of the oral exam considers the acquired knowledge, the comprehension of the subject and the ability to properly present the topic.

Disabilità e DSA

Le studentesse e gli studenti che hanno registrato la certificazione di disabilità o la certificazione di DSA presso l'Ufficio Inclusione e diritto allo studio, possono chiedere di utilizzare le mappe concettuali (per parole chiave) durante la prova di esame.

A tal fine, è necessario inviare le mappe, due settimane prima dell’appello di esame, alla o al docente del corso, che ne verificherà la coerenza con le indicazioni delle linee guida di ateneo e potrà chiederne la modifica.
