A transmitter includes: multiple digital transmitters which perform delta-sigma modulation on the same baseband signal; a combiner that combines the output signals from the plural digital transmitters and outputs the combined result; a control unit that generates an external signal different for every digital transmitter, to be supplied to each of the digital transmitters; and, an input means that supplies the different external signal for every digital transmitter, to the input terminal or the internal node of a delta-sigma modulator that performs the delta-sigma modulation, the delta-sigma modulator being provided for every digital transmitter. |
