Abstract

An additional driver (4) has pair of output terminals that are connected to a load (Z2), whereas input terminals are connected to output terminals of signal source for generating signals across the load. A receiver (2) connected to the load subtracts the signals generated across the load from the signals appearing on the transmission line to cancel echo, distortion and noise.
