differential signaling

(redirected from differential configuration)

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.

Differential vs. Single-Ended
Differential signaling 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 LVDS and SCSI.

For the purposes of high CMRR and low offset at the input, differential configuration with a symmetrical floor planning in layout will be preferred in the design of an amplifier.

But if a scholar reproduces this view, she closes the door on certain possibilities for analyzing the relations between persecutors and their victims--relations which could, even within this context of compulsion, have had a partially differential configuration.
Differential measurement techniques then can be applied to the network in the single-ended differential configuration. An example of the derivation and measurement is applied to a code-division multiple access (CDMA) surface acoustic wave (SAW) filter used in a dual-mode portable radio.
Under this contract, MEMSCAP provides Meggitt with standard and tailored versions of its TP 3100 pressure module transducers in both Absolute and Differential configurations, which have been designed and qualified to be completely integrated into Meggitt Air Data Units.
The amplifiers are suited for instrumentation applications, because their bandwidth reaches DC, and for differential configurations, because they maintain high signal integrity by delivering high linearity and low harmonic distortion.
These units are available in gauge, absolute, or differential configurations and have barbed pressure ports for secure tubing attachments.
