Abstract
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 one of four resistor banks, as determined by an automatic selection system that selects one of the resistor banks based on the measured transmission characteristics of the twisted pair. The output signals are weighted by the resistors of the selected resistor bank, summed, and used to generate the transmitted pulse. The values of the resistors of each resistor bank are chosen to shape the transmitted pulse for a respective length of transmission medium 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.
