LONGITUDINAL VOLTAGE

A voltage induced or appearing along the length of a transmission medium . Note 1: Longitudinal voltage may be effectively eliminated by using differential amplifiers or receivers that respond only to voltage differences, e.g., those between the wires that constitute a pair. Note 2: Induced longitudinal voltages at low ( power - line ) frequencies can be greatly reduced by twisting parallel wires to create what are referred to as "twisted wire pairs." Synonym common-mode voltage.
