Abstract
A wiring apparatus for reducing electromagnetic interference between conductive wires is provided. Wire pairs are incorporated into rigid or flexible printed circuits to precisely control loop alignment and phase differences. This precise alignment helps to cancel radiated electromagnetic fields and reduce voltage polarities induced in nearby wires. In one embodiment, a pair of parallel wires is aligned parallel to a second, twisted pair of wires. In another embodiment, two twisted pairs of wires, with identical loop lengths, are aligned parallel to each other and offset by exactly one half loop length. In a third embodiment, two twisted pairs of wires are aligned parallel to each other, in which one pair has a loop length that is an integer ratio of the other pair.
