摘要：
Tunable notch filters and control loop systems and methods can include a tunable notch filter providing a stop band, a sensing circuit in communication with the tunable notch filter and adapted to determine a phase change between a reference signal and a signal reflected from the tunable notch filter, and a control loop in communication with the tunable notch filter and the sensing circuit, the control loop being operable to adjust the tunable notch filter to modify the phase change.
