Echo and distortion cancellation arrangement for line driver, includes receiver which cancels disturbances of incoming signals by subtracting signals generated across load from incoming signal

摘要

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.
