ABSTRACT:
An adaptive transmission line termination which includes a variable voltage controlled resistor (16) connected either in series with the sending end of transmission line (10) or in parallel with the receiving end of line (10). The resistance of resistor (16) is varied in dependence upon the half voltage appearing on line (10) in order to match the characteristic impedance of line (10) for the series or source termination case. In the parallel termination case, the resistance of resistor (34) is varied in dependence upon the voltage appearing at the input of gate (14) to match the characteristic impedance of line (10).
