摘要 |
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 (20) according to the present invention receives a synchronization signal transmitted from a synchronization signal source (10) through a network. The synchronization apparatus (20) includes a frequency synchronization unit (21) that performs frequency synchronization based on a received synchronization signal, and outputs a frequency synchronization signal, a phase synchronization unit (23) that performs phase synchronization based on a synchronization signal transmitted from the synchronization signal source (10) through a network, and outputs a phase synchronization signal, and a phase synchronization control unit (22) 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. |
