Learning outcomes

At the end of the course, the student has the basic knowledge of digital communication systems technologies and telecommunication networks. In particular, the student is able to understand the characteristics of transmission media on cable, optical fiber and radio, the problems related to thermal noise generated in circuits, techniques for numerical modulation and channel coding.

Course contents

The course will follow a path similar to the organization of a system and a communication network. After an introduction to telecommunications and applications of Industry 4.0, to which the entire course will refer, we will move on to the fundamentals of communication theory by providing basic elements on the theory of signals and systems. Then the course will focus on the transmission media, considering electrical media, optical fiber and wireless medium. Then the course will concentrate on the description of physical layer (modulation) and its performance.

Below is a list of the topics covered in more detail.

  • Introduction to the course and to Industry 4.0
  • Fundamentals of signal and systems: PAM signal, LTI systems, distortion and filters, gain
  • Fundamentals of transmission media: coaxial cable, optical fiber and wireless medium, antennas, Friis formula
  • Physical Layer: modulation, thermal noise
  • Performance of Physical Layer: link budget, performance in the presence of thermal noise

Teaching methods

Chalk & talk - approx. 20 hours

Exercises - approx. 10 hours

Assessment methods

The exam is divided into two parts: a written and an oral part.

The written test consists of two exercises related to fundamentals of signals and systems, transmission media, link budget and modulation. The student will be allowed to consult the course notes during the exam. It will be possible to take the written test during the course: mid-term test carried out in the middle of the course.

The result of the written part (if positive) will be: passed, or passed with final mark limitation to 27, or passed with final mark limitation to 24.

Once the written test has passed (mid-term test or appeal in June / July), it will be possible to access the oral test.

The oral exam will consist of one question on the arguments addressed in the course.

The final grade is defined as follows: starting the oral with 30 (or 27, or 24 depending on the result of the written part) and decreasing the mark at each wrong answer.

Teaching tools

Theoretical part: books, slides, notes, in-depth material.
