Learning outcomes
Aim of the course
The course is intended to provide the students of Computer
Science Engineering with some basic concepts of Electrical
Communications. Given the student background, the theoretical
treatment, developed in a calssical way, will be complememted
by a great attention towards applications and economic aspects
to provide the students with the capability of an adequate
understanding of telecomunications technology and trends at the end
of the course. Moreover, the theoretical treatment will
be largely supported by informatic tools, both in lab and in
classroom.
Course contents
Lectures
The Comunications World: milestones in the development of
technology, applications and economic aspects.
Fourier analysis:representation of time-continous and
time-discrete deterministic functions in the frequency domain;
Fourier series and transforms, Dirac's Delta, transform of periodic
functions , FFT.
Generalized Fourier analysis: autocorrelation functions, energy and
power spectral density functions.
Linear circuits: transfer functions and impulse response.
Non-distortion conditions,ideal filters, real filters, FIR..
Digital conversion of analogue signals: sampling, PCM, uniform e
logarithmic quantization, ADPCM, vocoder basics, perceptual coding,
basics of MPEG audio and video coding standards..
Modulation Theory: general aspects and definition
of analogue modulations (AM, PM, FM, product, QAM), low pass
equivalent, spectra, basics of digital modulations.
Lab activities:
1) Analysis of a RC circuit;
2) sampling, spectra, ideal filters,
A/D techniques (GoldWave);
3) Study of AM.modulation in the time
and frequency domains.
