Abstract
An active termination circuit for a computer interface for reducing line reflection of logic signals. A first and second resistor combination is permanently connected to a cable that couples a plurality of peripheral devices to one another. The other ends of the first and second resistors are connected through a switching device to a positive voltage supply line and to logic ground, respectively. That switching device may be a transistor. When termination of multiple devices is required, a plurality of resistor combinations is provided but on/off control of the switch is achieved by one control that is located remote from the termination circuit.
