Abstract
A method to adjust a waveform transmitted from a field device to overcome cable bandwidth limitations by passing data to be transmitted through a channel compensation device which pre-distorts data to be transmitted to compensate for the bandwidth limitations. The predistortion may make sure that there is a good quality signal received at the control end of the cable.
