Electrical Termination




Electrical termination of a Signal involves providing a '''terminator''' at the end of a wire or cable to prevent an RF signal from being reflected back from the end, causing Interference . The terminator is placed at the end of a Transmission Line or Daisy Chain Bus (such as in SCSI ), designed to Match Impedance and hence minimize signal Reflections .


TYPES OF TERMINATORS


Simple resistor


Often the terminator is a Resistor . There are also active terminators which contain an Electric Circuit to perform the same basic function.


Dummy loads

See Also: Dummy load


Dummy loads are commonly used in HF to EHF frequency circuits.


50 ohm


10BASE2 networks absolutely must have proper termination with a 50 ohm BNC Terminator . If the bus network is not properly terminated, too much power will be reflected, causing all of the computers on the bus to lose network connectivity.


75 ohm


A terminating resistor for a television cable is often in the form of a cap, threaded to screw onto an F Connector . It is nicknamed " Schwarzenegger device".


OTHER MEANING

Electrical termination sometimes refers to manufacturing operations which connect wires together. This includes Crimping , Soldering , and related operations.
