摘要： A communication device of the disclosure includes a phase synchronizer, a modulator, and a controller. The phase synchronizer generates a second signal on a basis of a first signal received from a communication partner by selectively performing one of a closed loop operation and an open loop operation. The modulator is able to modulate the first signal on a basis of the second signal. The controller controls operations of the phase synchronizer and the modulator.

摘要： The present technology relates to a first edge detector that detects whether there is an edge of a second clock signal in one cycle of a first clock signal. A second edge detector detects whether there is an edge of the first clock signal in one cycle of the second clock signal. The logic circuit performs a logical operation on a detection result from the first edge detector and a detection result from the second edge detector. The present technology can be applied to a circuit or the like that detects a locked state of a PLL circuit, for example.
