1. A transmission device, comprising:
a driver configured to transmit a transmission signal that includes at least two signals;
an alternating current signal generator that includes a phase-locked loop circuit, wherein the alternating current signal generator is configured to:
generate a first alternating current signal of a plurality of alternating current signals;
set a first phase of the first alternating current signal; and
set a frequency of the first alternating current signal;
an amplifier configured to:
amplify the first alternating current signal generated by the alternating current signal generator; and
set an amplitude of the first alternating current signal; and
a superimposer that includes at least two capacitors, wherein the at least two capacitors are configured to superimpose the first alternating current signal amplified by the amplifier on the at least two signals.
