Abstract
One embodiment of the invention provides a method, system, and apparatus to update an adaptive filter real-time based on pre-determined filter configurations. When it is determined that an adaptive filter should be updated, a request is made for an updated filter configuration. An updated filter configuration is provided from a storage device that stores multiple pre-determined filter configurations for various operating conditions.
