Abstract: The present invention is directed to an electrical testing device for use in an AC electrical power distribution circuit including a plurality of AC electric power transmitting wires coupled between an AC power distribution point and a device box. The device includes a plurality of electrical probes configured for insertion into an outlet receptacle. A plug test connection arrangement is configured to receive a plug connector when inserted therein. The plug connector includes a plurality of plug contacts and a termination arrangement configured to terminate the plurality of AC electric power transmitting wires such that electrical continuity is established between the AC power distribution point and the plurality of plug contacts. The plug test connection arrangement includes a plurality of test contacts configured to mate with the plurality of plug contacts when the plug connector is inserted into the plug test connection arrangement.

Abstract: A system for enhancing sound quality comprising a filter that square roots the instantaneous amplitude of frequencies in an input signal for generating artificial harmonics corresponding to said frequencies. The system can comprise an automatic level control that momentarily boosts the amplitude of artificially generated harmonics to emphasize attack transients occuring within the input signal.
