Abstract: Methods and apparatus of connecting and communicating signals between electrical devices (such as stereo or video speaker or interconnect cables or similar circuits) include applying a bias voltage across the dielectric without interfering with the signals, by applying an energy source to at least one conductor not in the signal path.

Abstract: A low distortion cable made of multi-strand conductors including a dielectric core, a plurality of conductive strands of solid cross-section wrapped around the core in a single layer and a plurality of dielectric spacer strands, at least one of which is interspersed between each adjacent one of said conductive strands to form therewith a single layer of alternating conductors and dielectrics about a core. The support for the conductive strands is only at the lines of contact with adjacent strands and the core. A dielectric insulatr surrounds and supports the layer of strands and core in a unitary assembly, the interstices between strands and dielectrics, where not in contact along lines of support, being filled with a dielectric gas, such as air.
