Abstract: A digital communication system comprises a transmitter including a (1,0) precoder for precoding a unipolar input digital data stream and a bipolar converter for converting the output signal of the (1,0) precoder into a bipolar signal. The bipolar signal is transmitted through a metallic transmission line to a receiver. The receiver comprises a digitizer for digitizing the transmitted signal to and a line equalization filter for equalizing losses encountered during propagation through the transmission line. A (1,1) converter is provided for converting the output signal of the line equalization filter in a manner opposite to the bipolar converter. A clock recovery circuit derives sample timing pulses from the output of the line equalization filter. A decoder responds to the sample timing pulses to detect symbols from the output signal of the (1,1) converter to generate a replica of the original digital data stream.
