Course description

Knowledge and understanding:
Thanks to the strict methodology of the scientific subjects
the student matures skills and understanding skills
necessary for subsequent studies

Ability to apply the knowledge and
comprehension ability:
The didactic setting contemplates that theoretical training is
by exercises that solicit the active participation, proactive attitude and the ability to autonomous processing.

Autonomy of judgment:
The proposed topics allow the development of the ability to understand and adapt learned approaches to cases other than those proposed in the classroom.

Communicative Skills:
The course setting is such that the student will develop proper language properties and will use it to use unambiguous terminology, proper to signal theory

Ability to learn independently
The proposed exercises are designed to develop the ability to identify important aspects before dealing with the exercise itself

Prerequisites

Knowledge of basic tools of mathematical analysis

Learning assessment

The aim of the final exam is to check the level of achievement of the goals previously indicated.
The exam is divided into 2 parts:
- a written part that consists in the resolution of some exercises. The proposed exercises are of the same type as those presented and solved in classroom.
- an oral part on all the thematic presented in the course; The aim of the test is to evaluate the ability in studying course topics and in understanding basic arguments.
The final mark is given by the weighted average (0,4 and 0,6) of the scores of the 2 parts.
