ABSTRACT:
A method and apparatus for recovering at least one signal of interest are provided. The method includes receiving an overall signal, the overall signal including the at least one signal of interest and a plurality of other signals, identifying at least one of the strongest components of the plurality of other signals, attenuating, using at least one MEMS resonator, any of the components identified by the identifying, wherein the overall signal will be modified to include the at least one signal of interest, attenuated versions of the components identified by the identifying, and the remaining portions of the plurality of other signals that were not subject to the attenuating, and recovering, after the attenuating, the at least one signal of interest.
