Single-ended
From Wikipedia, the free encyclopedia
For other uses, see Single-ended (disambiguation).
There are two methods by which logic signals are transmitted over a cable. The first, called single-ended (SE), applies a positive voltage to a signal line. The current flows down the signal line to the receiver and returns through a common ground. This technique is less expensive to implement, but its limitations are that the signal cannot be transmitted over long distances or quickly. SE is the SCSI standard, and viable cable lengths range from 1.5 meters to 3 meters.
