Abstract
A method and apparatus for modifying or controlling a resonator connected to a signal loop having an input, an output, and a closed loop frequency response. The signal loop has a primary resonator having a primary frequency response. There is at least one adjustable resonator having an adjustable frequency and a secondary Q-factor. An adjustable scaling block applies a gain factor. A controller is connected to the at least one adjustable resonator and the adjustable scaling block. The controller has instructions to adjust the closed loop frequency response toward a desired closed loop frequency response by controlling the adjustable frequency of the at least one adjustable resonator and the gain factor of the adjustable scaling block.

A resonant circuit, comprising:
- a signal loop having an input, an output, and a closed loop frequency response, the signal loop comprising:
- a first component comprising a primary resonator, the primary resonator having a primary frequency response;
- and
- a second component comprising at least one adjustable resonator, the at least one adjustable resonator having an adjustable frequency;
- and
- an adjustable scaling block applying a gain factor;
- wherein the first component is fabricated from a first material, and the second component is fabricated from a second material that is different than the first material;
- and
- a controller connected to the at least one adjustable resonator and the adjustable scaling block, the controller comprising instructions to adjust the closed loop frequency response toward a desired closed loop frequency response by controlling the adjustable frequency of the at least one adjustable resonator and the gain factor of the adjustable scaling block.
A method of modifying a closed loop frequency response of a resonant circuit, comprising the steps of:
