Abstract
A method includes transmitting a data signal generated by adjusting a phase of a data signal, receiving a control signal having a frequency lower than that of the data signal and used to control an apparatus of a transmission destination of the data signal, and applying, in a case where a signal level of the control signal is a level, jitter to the data signal by periodically changing a magnitude of an additional phase code to be added to a phase code representative of an adjustment amount for the phase but fixing, in a case where the signal level is a level different from the level, the additional phase code to 0, receiving the data signal and adjusting a phase of the data signal to generate a data signal and restoring the control signal from a phase code representative of an adjustment amount for the phase.
