Learning objectives

Knowledge and understanding
The main goal of this course is to provide students with the ability to understand:
- the analog communication systems and the elements for their design, selection, and analysis;
- the digital communication systems and the elements for their design, selection, and analysis.

Applying knowledge and understanding
The abilities to apply the acquired knowledge and understanding result to be:
- design and analyze the performance of analog communication systems;
- design and analyze the performance of digital communication systems.

Prerequisites

Signal Theory

Teaching methods

Lectures and exercises (approximately with a ratio 70%-30%). For the latter, the teacher will solve on the blackboard the exercises assigned to the students one week in advance. In this way, the students can try to solve them at home, will take advantage much more of the interaction with the teacher, and can explain their work.

Assessment methods and criteria

Written and oral exams. It is required to pass the written exam to be admitted to the oral exam. The final mark will be the arithmetic mean of both marks. The written exam is about the design and analysis of a digital communication system, the oral exam on the theoretical aspects. Intermediate written exams will be considerated upon students' request. A final project using Matlab is also foreseen.
