Abstract:
A data communication apparatus includes a band-elimination filter configured to perform a process of reducing a specific frequency component included in transmission data, a packet producer configured to produce packet data including therein data outputted from the band-elimination filter, and an antenna configured to output the packet data produced by the packet producer, and further, the band-elimination filter is configured to reduce a frequency component corresponding to the reciprocal of a packet transmission cycle inherent in the packet data.
