Abstract
An extracting assembly for extracting a component signal generated by a component source from a composite signal is disclosed wherein a reference sensor generates a reference signal relating to activity of the component source, a composite sensor senses the composite signal, an adaptive filter is operatively connected to the reference sensor and the composite sensor to filter the component signal from the composite signal as a function of the reference signal generated by the reference sensor, and a normalizer operatively connected to the adaptive filter for normalizing the step size of each iteration taken by the adaptive filter to minimize the time to adapt the adaptive filter to transform the reference signal into the component signal.
