ABSTRACT:
A network synchronizer apparatus for synchronization between a primary apparatus and a remote apparatus is described. One of the apparatus receives a message signal from the other one, and produces a sync signal which is desired to be synchronized with the message signal. The snyc signal is delayed by a selectable amount to produce a delayed sync signal, and the apparatus determines which of the signals arrived first. An interval between the arrival of these signals is detected. An amount of delay produced for the delayed sync signal is then controlled in order to minimize the interval.
