'''Common-mode interference''' (CMI) is a type of common-mode signal. Common-mode interference is interference that appears on both signal leads, or coherent interference that affects two or more elements of a network.

In most [[electrical circuit]]s, adesired common-modesignals signal isare transferred by a differential voltage between two [[Electrical conductor|conductors]]. If the voltages on these conductors are {{math|''U''₁}} and {{math|''U''₂}}, the common-mode signal is the [[Arithmetic mean|average]] of the voltages:
