<p>To provide a digital modulator including: a signal adjuster (105) which is provided with a plurality of output lines, and which outputs, to the output line, which corresponds to a range to which a level of an input signal belongs, a signal of a level corresponding to the level of the input signal; a plurality of internal digital modulators (111-1 to 111-N), each of which is provided so as to correspond to each of the plurality of output lines and carries out delta-sigma modulation on the signal of the corresponding output line to output the modulated signal; and an encoder (113) which encodes the plurality of modulated signals respectively outputted by the plurality of internal digital modulators.</p> |
