Abstract
The present disclosure relates to a method and system for tone signal removal from a noisy signal that includes a desired signal in combination with the tone signal. The method and system provides an artificial or estimated undesired tone signal with the same frequency as the undesired tone signal, which, in combination with an estimated phasor, is available to filter or subtract a noisy component from the noisy signal and to provide the filtered or clean desired signal.
