ABSTRACT:
A signal shielding structure for a cable, such as an audio cable, employs 1) a shielding sheath which is electrically insulated from and encloses the signal-carrying conductors in the cable and 2) one or two discrete inductors electrically coupled between selected discrete points of termination on the shielding sheath and selected ground points to provide a d.c. signal path to ground and to inhibit ground termination of r.f. signals. The shielding sheath floats and is preferably everywhere electrically isolated from direct-wire connection with all grounds and all signal sources except for the connection through the inductor or inductors.
