The course aims to treat the basic elements of telecommunications. Starting from the signals theory, it will be processed the main concepts of telecommunications theory . Particularly we will study the techniques of transmission and reception of various types of channels: electrical cables, radio channels and optical fibers |
|
calculation and linear algebra |
|
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). |

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 |
