Abstract
An apparatus and method for mitigating noise in a waveform from a signal-producing device. The method includes receiving the waveform from the signal-producing device, and decomposing the waveform into low frequency (LF) and high frequency (HF) components. The method also includes determining an instant amplitude of the HF component, and employing the instant amplitude of the HF component and possibly the LF component to obtain a noise correction value for the LF component. The method further includes adding the obtained noise correction value to the LF component to obtain an output signal.
