Obiettivi

This course provides the basics for understanding the techniques of transmitting information in a generic communications system and for its protection against noise and disturbances superimposed. At the end of the course students will acquire the basic knowledge for understanding, characterization and transmission of the main signals: audio and data.

Modalità d'esame

The assessment of the students degree of preparation will be made, first, by establishing the ability to translate theoretical knowledge in simple design examples. The examination will consist of a written test, whose score above a minimum threshold represents a pre-requisite to proceed with the next stage of evaluation. This will consist of an oral interview which will aim to check the understanding of the concepts provided in the course. Particular attention will be reserved to the student's ability to make connections between the various treated topics and to assess their impact in a real telecommunications system. There are no intermediate checks other than those arising from the daily interactions during lessons and individual meetings between teacher and students. Based on the perceived level of preparation the teacher could calibrate the contents of the course. An optional  check will be made, for students who will request it, through the development of a research paper on a topic of the course. The evolution of this integrative study activity will provide to the teacher more individual elements of assessment, usable also for the final exam. Exam booking must be done exclusively via the internet at segreteriavirtuale.univaq.it / Start.do.
