The work described in this thesis deals with the study and characterization of synchronization systems used at RF and microwave bands, mainly to achieve symbol synchronization in high bit rate digital communications. First, feedhack systems are studied with special attention given to the phase locked loop with injection (PLLI). Afterwards the problem of syrzchronization of signals with open loop structures is a...
