Abstract
A filter controller. In one embodiment, the filter controller includes a first mechanism for providing an input signal to an adjustable filter. A second mechanism measures a response of the adjustable filter to the input signal and provides a second signal in response thereto. A third mechanism sets one or more parameters of the adjustable filter in response to the second signal. In a more specific embodiment, the adjustable filter includes one or more sub-filters, such as a canceller filter, which may be any filter that employs one or more portions or versions of a signal to selectively cancel one or more portions or versions, such as frequency components, of the same signal.
