Abstract
Provided is a modulation apparatus that outputs an output signal having a designated amplitude and a designated phase, comprising a first variable delay section that outputs a first delayed signal obtained by delaying a periodic signal by a set delay time; a second variable delay section that outputs a second delayed signal obtained by delaying the periodic signal by a set delay time; an adding section that adds together the first delayed signal and the second delayed signal, and outputs the result as the output signal; and a setting section that sets the delay times for the first variable delay section and the second variable delay section according to the designated amplitude and the designated phase.
