Prerequisites
This Course requires the knowledge of the basic concepts of mathematical analysis.

Learning outcomes
To know and understand the techniques for information transmission in a generic communication system, both analog and digital, and its protection against noise and disturbances, in such a way as to guarantee link reliability. To be able to measure the amount of information generated by an information source and the means to represent it by physical signals.

Program
- Deterministic signals and their representation in the time and frequency domains. - Random signals. - Characterization of a telecommunication system. - AWGN channel. - Analog modulations. - Quantization. - Information sources and source coding. - Representation of digital signals over the AWGN channel and the band-limited channel. - Demodulation and quality in digital transmissions over the AWGN channel and the band-limited channel.

Development of the examination
LEARNING EVALUATION METHODS
The evaluation of the learning level is organized in two tests: - A written test, consisting in the solution of two exercises, the first one on Signal Theory and the second one on Telecommunications, to be completed in approximately one hour (the exact time is determined by the difficulty level established for the exercises). - An oral test, consisting in the discussion of two or more topics of the course. The written test is propaedeutic to the oral test, in the sense that the student is admitted to the oral test only if he has received a sufficient evaluation in the written test. The oral test should be stood, preferably, in the same session of the written test. Deviations from this rule are possible, but must be agreed with the teacher before starting the written test. In case of negative evaluation of the oral test, the student can decide to retain the result of the written test or to repeat it in the subsequent sessions. The chosen option must be communicated to the teacher before starting the new exam session the student wishes to attend.

LEARNING EVALUATION CRITERIA
Learning evaluation is based on the verification, through the tests described above, that the student has acquired a sufficient level of understanding and a suitable capacity of employing the topics presented throughout the course, as regards both the fundamentals of signals and their application in telecommunication systems.

LEARNING MEASUREMENT CRITERIA
For the written test, the teacher assigns a score that, as a function of the quality of the paper, can be: not sufficient, sufficient, adequate, good, very good, excellent. The student is non admitted to the oral test if his score is not sufficient. Any positive score (sufficent or more), by which the student has been admitted to the oral test, permits the student to reach the maximum final score (thirty, cum laude if applicable) if he is able to demonstrate that the gaps shown in the written test do not correspond to real deficiencies in the preparation. The final score, in thirtieths, is the result of the global evluation on the oral and written tests.

FINAL MARK ALLOCATION CRITERIA
In order to pass the exam, the student must reach at least a sufficient score in the written test and show an adequate preparation in the oral test. The maximum score is reached by showing a deep knowledge of the course topics throughout the tests. Laude is reserved to those students who are particularly brilliant in the oral test, even able to compensate in an excellent way possible gaps appeared in the written test.
