Knowledge
The student who successfully completes the course will be able to demonstrate a solid knowledge and understanding of analog and digital communication systems with a special emphasis on system design and performance analysis in the presence of additive gaussian noise. The student will acquire ability in dealing with noise characterization and calculations in communication systems; waveform coding (PCM, DPCM, DM); complex envelope representation of bandpass signals, random processes and systems; PLL for FM demodulation and carrier phase and frequency synchronization. The student will be aware of the main analog and digital amplitude and angle modulations and the relevant performance analysis, in the presence of noise.
Assessment criteria of knowledge
In the written exam, the student is asked to solve some exercises in order to demonstrate his/her knowledge of the course material and to organise an effective and correctly written reply.
During the oral exam, the student will be assessed on his/her ability in discussing the main course contents
with competence, critical awareness and propriety of expression.
Methods:
- Final oral exam
- Final written exam
- Periodic written tests
Further information:
The final test is composed by a written exam followed by an oral one. In general, both each part contributes
50% to the definition of the final grade.
