Definitions for "Differential Mode Noise"
Keywords:  ripple, noise, excluding, mode, respect
The conducted noise of an output as referenced to its return path. This is typically how "ripple and noise" specifications are defined.
Noise that is measured between two lines with respect to a common reference point excluding common-mode noise. The resultant measurement is the difference of the noise components of the two lines. The noise between the DC output and DC return is usually measured in power supplies.
The component of noise measured between DC output and output return.
