Line 11: Common-mode signals may be effectively eliminated by using [[differential amplifier]]s or receivers that respond only to voltage differences, ''e.g.,'' those between the wires that constitute a pair. Induced common-mode signals at low ([[Electric power transmission\|power-line]]) frequencies can be greatly reduced by twisting parallel wires to create [[twisted wire pair]]s. ~~Example: lets take a three phase system having current Ia, Ib, Ic.~~ ~~then common mode current is avg of the sum of the currents.~~ ~~Icm = (Ia + Ib + Ic)/3;~~ == See also ==
