Introdução às Telecomunicações

The aim is to provide the students with knowledge on the classic modulations, namely PCM, AM, FM, and digital modulations, and also knowledge on basic multiplexing techniques (in time and frequency). It is intended that the students become familiarized with the time and frequency descriptions of signals and systems, as well as the concepts of signal bandwidth, sampling, and spectral density of signals. To achieve these goals the students must understand the functionally of electronic devices as filters, multipliers, sample-and-hold, etc. The laboratorial component will provide the students with a direct contact with systems that execute the subjects studied in the theoretical part.
