ABSTRACT:
An electromagnetic and/or electric interference suppression device that reduces the severity of electromagnetic and/or electric interference of an asymmetric system. The suppression device utilizes an antenna to develop a voltage that is ideally equal to the interference voltage developed from interference signals. A tuned circuit having two opposing diodes, a capacitor, and an inductor mounted in series with each other, to create a voltage that approximates as closely as possible the interference voltage, neutralizing its effect on an asymmetric system.
