Abstract:
An arrangement for transmitting digital data output by a first device to a second device over a twisted pair wire, the arrangement comprising:a modulator configured to receive a data signal output by the first device and modulate the data signal to produce a corresponding modulated data signal using at least one radio frequency (RF) carrier; and a line driver configured to receive the modulated data signal and output the modulated data signal through at least one twisted pair wire to the second device based on a carrier sense multiple access (CSMA) protocol, wherein the modulator further includes a first filter that is configured to low pass filter the data signal, and wherein the first filter is a low pass filter having a pass band equal to about 88 percent of a data rate of the digital signal and is selected from a group of low pass filters consisting of a fifth-order Butterworth low pass filter and a Gaussian low pass filter.
