Abstract:

Systems, methods, and computer program product embodiments are disclosed for filtering noise from an input signal. An embodiment accesses the input signal having a first harmonic frequency and having the noise. The embodiment determines a quiet period in the input signal. The embodiment stores samples of the noise of the input signal in a buffer during the quiet period. The embodiment subtracts the samples from a single cycle of the noise in the buffer from the input signal to create a filtered signal. The embodiment then repeats the determining, storing, and subtracting to refine the filtered signal.
