Abstract
Abstract A power strip for use in high definition audio and video systems employing a device having a digital switching source is disclosed. The power strip includes a first receptacle for the digital source employing capacitors for shunting to ground high frequency products at the digital receptacle. The strip includes additional receptacles for non-digital devices, the additional receptacles being isolated from the digital receptacle by series inductances and also being isolated from ground.
