The Why and How of Differential Signaling - Technical …

Differential Signaling Differential signaling, which is less common than single-ended signaling, employs two complementary voltage signals in order to transmit one information signal. So one information signal requires a pair of conductors; one carries the signal and the other carries the inverted signal.
Balanced and Differential - Hairball Audio
https://www.hairballaudio.com/blog/resources/diy-resources/balanced-and-differential
The differential input senses a signal by measuring the voltage difference between conductors. Signal voltages common to both conductors (the noise) are ignored. So in an impedance balanced line that has a 1V signal on one conductor and no signal on the other (0V), the input would pass a 1V signal ( the difference between the two conductors).
Is audio signal passing through headphone differential ...
https://electronics.stackexchange.com/questions/349890/is-audio-signal-passing-through-headphone-differential
Technically, the signals are not differential, because there is a ground. But in reality, how can you even tell the difference? There are just two wires at each speaker with a voltage between them. The speaker (inside the headphone) has no way to know if the signal is differential or ground-referenced, and it really doesn't care.

The differential signal will be fed directly into the audio amplifier. 4. An op amp creates an inverted signal into a differential audio amplifier. An alternate to using the op amp to create a differential signal is to use a 1:1 transformer. This transformer simplifies the circuit, but can add some size, particularly height, to the solution.
conversion of single ended audio input to differential ...
https://electronics.stackexchange.com/questions/95796/conversion-of-single-ended-audio-input-to-differential
To connect your single-ended audio signal to the differential input is easy: connect the inverting input of the differential input to ground, and the ground-referenced audio signal to the non-inverting input. To make a differential signal, you need two signal lines with equal impedances that carry the signal in their difference.

Signal conditioning, differential to single-ended amplification Sylvain Colliard Piraud Introduction There is a wide range of applications for which we need to amplify a differential signal and convert it into a single-ended signal. Such applications can be used to condition the signal

Figure 3. Fully-differential modes vs. single-ended is doubling ADC dynamic range. Another way to think about this is in relation to signal-to-noise ratio (SNR). The SNR is defined in terms of the ADC's full-scale input level and the minimum detectable signal: The minimum detectable signal is typically limited by the noise floor.
