Abstract
A synchronization apparatus capable of reducing the effect of the fluctuations in synchronization signals that are caused when the synchronization signals are received through a network are provided. A synchronization apparatus () according to the present invention receives a synchronization signal transmitted from a synchronization signal source () through a network. The synchronization apparatus () includes a frequency synchronization unit () that performs frequency synchronization based on a received synchronization signal, and outputs a frequency synchronization signal, a phase synchronization unit () that performs phase synchronization based on a synchronization signal transmitted from the synchronization signal source () through a network, and outputs a phase synchronization signal, and a phase synchronization control unit () that generates an offset value by using a phase difference between the frequency synchronization signal and the phase synchronization signal, and corrects a phase of the frequency synchronization signal by using the offset value.
