differential signaling
(redirected from Single-ended signaling)

   Also found in: Wikipedia 0.01 sec.
differential signaling
Using two wires for each electrical path for high immunity to noise and crosstalk. The signals are sent down one wire as positive and the other as negative, and the circuit at the receiving end derives the signal from the difference between the two. It is superior to single-ended signaling, where the reference voltage is ground and can vary over long distances. In differential signaling, the reference voltage is controlled. Typically, twisted pairs are used so that external radiation impacts both wires at the same place, and the noise can be detected more easily. See SCSI.

21) [FIGURE 10 OMITTED] Application of Mathcad for simulating such single-ended signaling is demonstrated by FIGURES 11 and 12.
[FIGURE 4 OMITTED] Differential pairs are used to specifically create a closely coupled return path for the signal, eliminating most of the single-ended signaling problems (like the aforementioned twisted pair).
The shielding is flexible to allow for column differential, row differential (for within-pair skew reduction), and single-ended signaling.
