Abstract
Disclosed herein is a carrier synchronizing circuit including at least frequency synchronizing means and phase synchronizing means. The phase synchronizing means includes residual frequency error detecting means for detecting a residual frequency error after a frequency synchronizing process by the frequency synchronizing means and supplying the residual frequency error to the frequency synchronizing means, and the frequency synchronizing means performs frequency pull-in for the residual frequency error supplied from the residual frequency error detecting means after first timing.
