ESTUDO ANALÃTICO E EXPERIMENTAL DO SINCRONISMO NAS REDES DE PLLs (PHASE LOCKED LOOP’s), EM TOPOLOGIAS MESTRE-ESCRAVO

Abstract

The study of the synchronism is present in many areasof human knowledge, with huge importance in engineering, innetworks of computers, in telecommunications networks and,additionally in the physics and biology. In this article theperformance of telecommunications networks under someunavoidable internal and external effects is mathematicallydiscussed for topologies Master-Slave Single Chain and Single Link,in terms of the existence of synchronism and stability of this state.Through Simulink® software, the mentioned topologies aresimulated and after that, laboratory experimental tests are developedfor confirming and comparing the previous results obtained with themathematical analysis and simulation.Index Terms ⎯ synchronism, stability, Phase Locked Loop, PLL.
