differential duplex system

[‚dif·ə′ren·chəl ′dü‚pleks ‚sis·təm]
(electronics)
System in which the sent currents divide through two mutually inductive sections of a receiving apparatus, connected respectively to the line and to a balancing artificial line in opposite directions, so that there is substantially no net effect on the receiving apparatus; the received currents pass mainly through one section, or through the two sections in the same direction, and operate the apparatus.
