crosstalk
     
         Interference caused by two signals becoming
        partially superimposed on each other due to electromagnetic
        (inductive) or electrostatic (capacitive) coupling between the
        conductors carrying the signals.  A common example of
        crosstalk is where the magnetic field from changing current
        flow in one wire induces current in another wire running
        parallel to the other, as in a transformer.  Crosstalk can be
        reduced by using shielded cables and increasing the distance
        between conductors.
