Abstract
Reliable phase synchronicity between a local carrier signal and the carrier signal of an amplitude and/or phase shift keyed received signal is produced as quickly as possible by employing a phase detector characteristic whose root means square outside of the synchronization point is as large as possible and whose synchronization point, i.e., zero passage, is situated such that it also considers a phase deviation of the received signal component from its quadrature position.
