FIELD: information technology.
SUBSTANCE: method of data transmission features capability to modulate data into multiple carriers with different carrier frequencies which results in obtaining transmission signal; preset bandwidths of the mentioned signal are cutout as otherwise preset bandwidths would disturb external transmission; attenuation value of the mentioned adjacent carriers which are located adjacent to the mentioned bandwidths and which could be attenuated due to the mentioned cutting out step is determined, and the mentioned carriers are amplified by certain value. Modem for data transmission is intended to implement the Method of data transmission.
EFFECT: improvement of rejector filtration properties to work in systems for data transmission over electric mains.
