Master‐Slave Topologies with Phase‐Locked Loops
Wireless Communications and Mobile Computing, Volume 2020, Issue 1, 2020., 2020 Since phase‐locked loops (PLLs) were conceived by Bellescize in 1932, their presence has become almost mandatory in any telecommunication device or network, being the essential element to recover frequency and phase information. As the technology developed, PLL appeared in several applications, such as, dense communication networks, smart grids ...
