Terminator
From Computer History Wiki
(Redirected from Bus termination)
A terminator is a device (usually an ordinary resistor) used at the end of a transmission line to prevent energy (i.e. a signal) being reflected back down the conductor of the transmission line, and appearing as noise elsewhere on the tramission line. A terminator must have the correct size, matching the impedance of the transmission line, to properly damp out all reflections.
