Abstract
A communication system includes a phase-locked loop that maintains synchronization of a reception signal. The phase-locked loop includes a loop filter that has a circuit configuration m for an m-th order phase-locked loop including a circuit configuration n for an n-th order phase-locked loop (m>n), and a switching section that switches circuit configurations, which are activated in the loop filter, between the circuit configuration n and the circuit configuration m.
