(electronics)
In a circuit, a signal that is the voltage difference between two nodes, neither of which is at ground potential. Also known as floating signal.

I have found it more difficult to accommodate differential signal polarity in PCB routing for edge-coupled lines on connectors whose signal pin pairs are oriented parallel (rather than at right angles) to the connector body.
Many two-channel differential signal sources can generate I/Q signals but may not be able to address the issue of fully independent control of each differential line's parameters such as phase, amplitude, and DC offset.
Ideally, the magnetic flux produced by the differential signal currents has a cancellation effect and, for that reason, is not a large contributor of EMI noise.
Since these signals can be of different types, in addition to a modular combination for I&C signals with common reference potential (generally digital signals), HARTING also offers a combination for differential signal transmission or for transmission without a common reference signal.
However, because of the sampling error, the waveforms have little variation, resulting in a small residual noise in the differential signal. Meanwhile, since the reference signal is generated by averaging the signals in different position, the random noise is suppressed.
Utilizing transmissive optical sensing technology, they support applications requiring up to 2000 pulses per revolution and are available in both single ended and differential signal outputs for applications where noise immunity is critical.
has unveiled a low-voltage differential signal (LVDS) digital isolator series designed to improve performance, reliability and power consumption in industrial instrumentation and programmable logic controller (PLC) applications that previously required redesign of the interface to support LVDS signal isolation.
The results showed that rectangular probe could effectively identify the different width and depth of crack defects and with the increase of the notch depth or width, the peak value of defect differential signal increased [17].
Motivated by [26, 27], in this paper, a novel iterative algorithm with one-lag and multilag differential signal is proposed for the frequency rate estimation of Chirp signal.
Ideally, differential signal transmission methods meet the tight requirements of EMI compliance and signal integrity but, in practice, any differential signal has some level of common-mode noise (mainly caused by amplitude unbalance and time skew).
