Course description

- Knowledge and understanding: the student must demonstrate to know and be able to understand Telecommunication Systems and Networks, and the fundamental principles of Signal theory.
- Ability to apply knowledge and understanding: the student must demonstrate to be able to solve low complexity problems on fundamental signal and probability operations.
- Autonomy of judgment: the student must be able to develop the ability to critically analyze the different TLC systems, with particular reference to case studies different from those proposed during the course.
- Communication skills: The student must have the ability to express clearly and simply technical concepts and to use scientific language correctly.
- Learning skills: The student must be able to integrate and update knowledge using different sources.

Prerequisites

The basic mathematics of the Upper Secondary School.

Learning assessment

Two inter-course tests are foreseen for students in progress. The first downstream of the first didactic period and the second downstream of the second didactic period. Learners can also opt for a single exam at the end of the entire cycle of lessons. The objective of the examination tests is to verify the level of achievement of the previously indicated training objectives. The first intra-course test is divided into a series of multiple choice and free choice questions. The second intra-course test is divided into a part in which you are asked to solve exercises, and in a part in which oral questions are asked. The overall exam is divided into 2 parts: a written test and an oral test. - the written test consists in carrying out probability exercises, with the goal of assessing whether the student has the ability to analyze them e solve them with the methodologies addressed during the course. The result of the written test will fall into the following grading classes: A - (27-30); B (24-26); C(21-23); D (18-20); E (15-17); F (insufficient). The oral exam is admitted having obtained, in the written test, a grade equal to at least "E". The time required for the written test is at least 1 hour. It is not possible to consult material. - an oral test on the exam program.
