A digital data transmission system includes a transmitter connected to a receiver by a twisted pair. A digital transversal filter, included in the transmitter, supplies output signals to a resistor bank. The output signals are weighted by the resistors of the resistor bank, summed, and used to generate the transmitted pulse. The values of the resistors are chosen to predistort the transmitted pulse so that, after distortion by the transmission medium, the transmitted pulse more nearly corresponds to the ideal pulse shape for which the receiver is designed.
