Abstract
The purpose of the present invention is to improve signal modulation resolution. A coarse phase modulation elementA modulates a signal into any of M(Mis an arbitrary integer) patterns in a first range. Fine phase modulation elementsB-throughB-(k−1) respectively modulate the signal into any of Mthrough Mk (Mthrough Mk are arbitrary integers that are independent of each other and M) patterns in a second range through k-th range (k is an integer of 2 or greater). A coarse DACA and DACsB-throughB-(k−1) perform control such that the second range through k-th range become narrower than the first range.
