Learning outcomes

This course covers a large part of the telecommunications systems aiming at understanding the basic principles of analog and digital communication systems, which rely on wireless transmission of information. In particular, an introduction to the basic principles of analysis and design of telecommunications systems is considered, along with the transmission technologies of the physical layer. The theoretical and laboratory section of the course is a detailed presentation of all the necessary technical data, definitions, standards, essential for understanding Analog Communication Systems, a presentation of basic analog and digital modulation, coding techniques and effects of noise signals. Upon completion of this course the student will be able to understand the propagation of information and the govern techniques and also techniques necessary to implement basic telecommunications data transmission system. The laboratory part of the course involves the performing of laboratory exercises for in-depth understanding and consolidation of the basic principles of analog telecommunication systems, along with the familiarity of the laboratory instruments.


Signals and Systems, Stochastic Processes, Statistic.

Learning Activities and Teaching Methods

The main teaching method followed is the traditional face-to-face lectures in class. The lectures are accomplished with the help of an electronic presentation program using portable computer with suitable tripod projection screen and projector. Interactive images and videos are used for adequate understanding of the main disciplines of the course. In addition, lectures are given where problems and exercises are solved. An asynchronous distance learning software is used (eclass). All the presentations, resolved exercises, multimedia material, notes, exercises to be delivered, laboratory exercises, announcements, links, etc. are updated frequently in eclass. In the lab, students become familiar with laboratory equipment (oscilloscope, generator, power supply) and carry out specific exercises for better understanding of the theory.

• Written exams: 70%
