Line 1:
In [[telecommunication]], a '''paired disparity code''' is a [[code]] in which some or all of the characters are represented by two sets of digits of opposite [[disparity]] that are used in [[sequence]] so as to minimize the total disparity of a longer sequence of digits.
An [[Alternate Mark Inversion|alternate mark inversion signal]] is an implementation of a paired disparity code.
The digits may be represented by disparate physical quantities, such as two different frequencies, phases, voltage levels, magnetic polarities, or electrical polarities, each one of the pair representing a 0 or a 1.
