A modulation apparatus comprising a first modulating section that outputs a first modulated signal having a fixed amplitude and a set phase; a second modulating section that outputs a second modulated signal having the fixed amplitude and a set phase; an adding section that outputs the output signal as the sum of the first and second modulated signals; a calculating section that calculates two phases to be set respectively in the first and second modulating sections, based on designated amplitude and phase; an allocating section that allocates, for the first and second modulated signals, the two phases calculated by the calculating section such that the first and second modulated signals are each connected more smoothly; and a setting section that sets the phase allocated for the first modulated signal in the first modulating section and sets the phase allocated for the second modulated signal in the second modulating section.
A modulation apparatus that outputs an output signal having a designated amplitude and a designated phase, the modulation apparatus comprising:
A phase setting method for setting a phase in a modulation apparatus that outputs an output signal having a designated amplitude and a designated phase, wherein the modulation apparatus includes:
