Communication Systems

The aim of the course is to provide students with knowledge
about basic concepts of telecommunication systems. Specifically,
the course focuses on the principles of signal theory, studying
the properties of telecommunication signals and mathematical
transformations (Fourier, Hilbert) as essential tools for
communication signal analysis. The main objective of the course
is to learn the process of modulation of signals of analog
systems, through the study of Amplitude Modulation (AM), AM
systems, the process of decoding amplitude, systems of Angle
Modulation (Frequency Modulation - Frequency Modulation -
Frequency Modulation). Phase Modulation (PM)), and angle
demodulation procedures. The effect of noise on both amplitude
and angle modulation systems is also studied.

Learning the following basic concepts:
Telecommunication System (Analog and Digital Communications)
Representation of Signals and Systems with emphasis on the
Frequency field
Fourier transforms and their applications in Telecommunications
Filters and Signal Transmission through them
Width Modulation and Demodulation
Rectangular Amplitude Configuration - Frequency Division
