11. A method for recovering at least one signal of interest, comprising:
-
receiving an overall signal, the overall signal including a signal of interest component and an interference component; identifying dominant portions of the interference component; processing the overall signal to produce a processed overall signal, said processing comprising attenuating the dominant portions of the interference component using a MEMS filter bank without any significant attenuation of the signal component or the non-dominant portions of the interference component; and attempting to recover the signal of interest component from the processed overall signal. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)

21. An apparatus for reducing interference in an incoming signal traveling along a signal pathway, comprising:
-
a bank of MEMS resonators, each of said resonators having an ON and OFF state; each of said resonators having an individual resonance frequency range collectively defining a frequency range of the bank; an electrode having a first end connected to the signal path, and a body connected to each of said MEMS resonators; and each of the MEMS resonators having a pathway to ground; wherein each individual resonator within the bank responds to the signal as follows; when the individual resonator is ON and the signal includes a component at a frequency that falls within the individual resonance frequency range of the particular resonator, the individual resonator will resonate in response to the signal and at least partially shunt the component to ground, thereby attenuating that component of the signal with substantially no impact on portions of the signal at frequencies outside the individual frequency range; and when the individual resonator is OFF, or when the individual resonator is ON and the signal does not include a component at a frequency that falls within the individual resonance frequency range of the particular resonator, the individual resonator will have substantially no impact on the signal; wherein the bank of MEMS resonators is configured to attenuate portions of the signal while having substantially no impact on the remainder of the signal. - View Dependent Claims (22, 23, 24)

25. An apparatus for reducing interference in an incoming signal traveling along a signal pathway, comprising:
-
a plurality of banks of MEMS resonators; a plurality of amplifiers, each located downstream of a respective bank of MEMS resonators; the output of each amplifier being connected to an available downstream one of the plurality of banks of MEMS resonators, to thereby iteratively process the signal; a controller configured to receive the signal and the output of each amplifier, the controller being configured to issue control signals to individual MEMS resonators within the plurality of banks of MEMS resonators, and to thereby attenuate interference components in the incoming signal; and wherein a signal of interest will be recoverable from either the incoming signal or the output of at least one of the amplifiers. - View Dependent Claims (26)
