A method, apparatus and system for building a filter is disclosed. The receiver includes an adaptive array that has at least two antennas. These three methods are employed using conventional hardware andor software in CD or DVD players, which may optionally be modified. A second foil element is bonded to the second conductive device surface B and to the second conductive substrate surface B1 and provides a continuous conductive pathway from each device conductive surface to the substrate conductive surface.
