MODULATION DEVICE AND PULSE WAVE GENERATION DEVICE

摘要

Provided is a modulation device including a signal selection circuit selecting two carrier signals from a plurality of carrier signals having the same frequency and the same phase difference according to a defined control signal and outputting the selected carrier signals, and a phase interpolator adjusting the phase in smaller units than the phase difference between the plurality of carrier signals according to the control signal and modulating the frequency or the phase of the carrier signal into a baseband signal based on the carrier signals selected by the signal selection circuit to generate a carrier wave signal.
