Abstract

Systems and method are provided for implementing filters whose response automatically and continuously reconfigures between an all-pass response and a bandstop response as the power level of signals within their bandwidth changes. Embodiments of the present disclosure allow high power signals within a designable bandwidth to be strongly attenuated while minimally affecting signals in adjacent bandwidths and further allow low power signals in the designable bandwidth to pass with minimal attenuation.
