Grammar... shouldn't it have an article?
Shouldn't use the word "common" when defining "common-mode signal".
Line 1:
{{short description|Voltage common to both input terminals of an electrical device}}
 
In [[electrical engineering]], a '''common-mode signal''' is the identical component of [[voltage]] commonpresent toat both input [[Terminal (electronics)|terminal]]s of an electrical device. In [[telecommunication]], the common-mode signal on a [[transmission line]] is also known as '''longitudinal voltage'''.
 
In most [[electrical circuit]]s the signal is transferred by a differential voltage between two [[Electrical conductor|conductors]]. If the voltages on these conductors are {{math|''U''<sub>1</sub>}} and {{math|''U''<sub>2</sub>}}, the common-mode signal is the [[Arithmetic mean|average]] of the voltages:
