Abstract
(EN)
This transmission device comprises: a voice acquisition unit that acquires a voice signal SD; a wireless signal formation unit that forms a transmission signal ST including the voice signal SD formed by the voice acquisition unit; and a transmission unit that transmits the transmission signal ST. The transmission signal ST further includes a first tone signal SA, an identification signal SC that is superimposed on the first tone signal SA, and a second tone signal SB that follows the first tone signal SA. The voice signal SD is superimposed on the second tone signal SB.
