In an electronic apparatus and method for reducing interference in an EPM signal, there is provided (a) a signal line connected to a-signal electrode; and (b) a reference line connected to a reference electrode. The signal line and reference line are associated by being in close physical proximity for a substantial part of their lengths. Subtraction means subtracts an interference signal on the reference line from an interference signal on the signal line to enhance a desired signal on the signal line.
