'''Common-mode signal''' is the component of an [[analog signal]] which is present with one sign on all considered [[electrical conductor|conductor]]s. In [[telecommunication]], common-mode signal on a [[transmission line]] is known as '''longitudinal voltage'''.

In [[electronics]] where the signal is transferred with differential voltage use, the common-mode signal is called a half-sum of voltages:
