'''Crosstalk''' refers to [[noise]] caused by [[signal]] coupling from one [[conductor]] to another nearby one. There are two physical mechanisms which create this coupling: [[capacitor|capacitive]] and [[inductor|inductive]].

In the former, the [[electric field]] allows the two conductors to act as the two surfaces in a capacitor; just as a normal capacitor allows high-[[frequency]] signals to pass through it, so too here.

In the latter, changes in the [[magnetic field]] around the first conductor, as [[current]] flows through it, induce current flow in the second conductor.
