RESUMO

This text deals with aspects of synchronization in telecommunication systems, with emphasis on the operational functions of synchronous demodulation, signal regeneration, multiplexing/demultiplexing (TDM) and digital switching. The methods of carrier recovery, clock recovery, phase locked loop and elastic store are presented. The final goal consists on the description of network synchronization methods, in the plesiochronous (and plesiochronous with justification), master-slave and mutual synchronization modalities. The synchronization subnetworks are analised in terms of topology, safety, operation frequency and phases, and transmission phase delay compensation. The presentation is made in a didactical way, describing the problems and their possible solutions.
