Abstract
Ringing occurring in a digital signal to be transmitted, is reduced or suppressed. A transmission module Ma includes a transmitterconfigured to transmit a digital signal, a transmission antennaconstituted by a metal plate, or by a conductor formed on an insulator. The transmission antennais configured to be electromagnetically or magnetically coupled to a reception antennaof a non-contact reception module Mb for digital communication. A resistoris connected in series between the transmitterand the transmission antenna. The resistorhas such a resistance value that the resistorentirely blunts a waveform of the digital signal outputted from the transmitterso as to reduce or suppress ringing occurring in the digital signal. The blunted digital signal can be inputted into the transmission antenna
