OVERVIEW

The acquisition and trasmission of information through telecommunications systems and networks are essential to control and monitor industrial processes in particular in the electrical sector. Remote control and monitoring is based on fundamental parameters such as sensing, communication, computing, and control. In this perspective, the knowledge of telecommunication signals and networks is of great importance for the comprehension and design of future systems. 

AIMS AND CONTENT

LEARNING OUTCOMES

The module provides a unified view of the main topics of the telecommunications sector: representation and analysis of signals, transmission of signals on telecommunication channels, transmission of information through telecommunications networks. The theoretical principles underlying these issues will be briefly recalled along with the main techniques on which modern devices and telecommunications equipment are based.

AIMS AND LEARNING OUTCOMES

At the end of the telecommunication module a student will be able:

• to evaluate the properties of a signal (band occupation, power, periodicity,…);
• to design an analogical-digital transformation, a filter;
• to understand the operation and block diagram of systems for the digital transmission of signals in the baseband and for the multiplexing of signals (in baseband and bandpass);
• to characterize a random process in spectral and statistical terms including the operation of analog modulation equipment;
• to describe the main elements constituting a modern telecommunications network and the Internet;
• to define the main Internet interconnection elements: hubs, switches, routers, gateways, terminals;
• to design the main features of protocols acting at data link, network, transport, and application layer;
• to read and understand technical documents concerning telecommunication infrastructures for remote control and monitoring.

TEACHING METHODS

Lectures supplemented by possible practical tests in the laboratory.

EXAMS

EXAM DESCRIPTION

The exam consists of a written test consisting of 4 questions (2 for the signal processing part, 2 for the telecommunications network part) of identical value followed by an oral exam (for the signal processing part) or by a brief oral comment on the writing test (for the telecommunications networks part).

ASSESSMENT METHODS

The written test is aimed at checking the skills of the students

• to evaluate the properties of a signal (band occupation, power, periodicity,…),
• to design an analogical-digital transformation, a filter;
• to characterize a random process in spectral and statistical terms including the operation of analog modulation equipment;
• to describe the features of main elements constituting a modern telecommunications network both concerning the infrastructure and the protocols;
• to understand technical specifications concerning telecommunication infrastructures for remote control and monitoring;
• to design basic elements of protocols acting at data link, network, transport, and application layer

concerning:

1. technical knowledge,
2. methodology,
3. clarity of the description.

Students with learning disorders ("disturbi specifici di apprendimento", DSA) will be allowed to use specific modalities and supports that will be determined on a case-by-case basis in agreement with the delegate of the Engineering courses in the Committee for the Inclusion of Students with Disabilities.

FURTHER INFORMATION

Students with valid certifications for Specific Learning Disorders (SLDs), disabilities or other educational needs are invited to contact the teacher and the School's contact person for disability at the beginning of teaching to agree on possible teaching arrangements that, while respecting the teaching objectives, take into account individual learning patterns.
