The end, a boundary, a closing. Used when referring to the end point of a video signal. A video signal has a definite beginning and end and cannot be split, divided or “Y”ed. The signal can be looped in and out of different devices which are not terminated but at the end of the line a 75 ohm resistor must end or terminate the signal.
An impedance used to terminate a transmission line. For example; cables used for video distribution should be terminated with a 75 ohm resistor (terminator) at the last connector on the receiving end if it is not already terminated internally.
