Ingénierie Informatique (Academic Year 2013/2014) - Ingegneria Informatica (ad esaurimento)

Comunicazioni elettriche


CFU: 9
Langue du contenu:Italien
Description du cours
In this course we will explain the basic concepts of telecommunications. Beginning from the Signal Theory, we will explain the transmission techniques on several channels: electrical cables, radio channel, optical fibers.
Connaissances requises
Calculus 1 and linear algebra
Programme
Introduction to the theory of signals: deterministic Signals, Fourier transform, spectral analysis, definition of a signal band of, the transfer function and definition of bandwidth of a system, filters. Sampling theorem. Random signals, statistical characterization and hints on the power spectrum. Analog & Digital transmissions: Analog Sources, analog modulations (AM, FM). Digital transmissions: Sources numbers, quantization, PCM conversion and A / D and D / A. Digital modulations (ASK, PSK, FSK, QAM).

Entraînements
Exam will include three main points: one exercise and two Open questions Exercises will concern above all: -Convolution and Correlation exercises between known signal forms. -Fourier Transform method -TLC systems and filters To improve Exam simulation, it is suggested to try to break Convolution and Correlation exercises in three steps, aimed to: -to graph or describe signal in analytic -to perform the calc, trying the calculation way or the visual way (generally faster). -to graph results Exam will concern theory test. It is suggested to focus on Digital Transmission and analog modulations
