The course "Communication Systems" aims to provide students with knowledge about basic concepts
of telecommunications 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.
