Abstract:
A data processing system includes an adaptive notch filter operable to estimate an interference frequency in data samples, a convergence detector operable to determine whether the interference frequency converges on a value, indicating that the data samples contain interference, and an interference removal circuit operable to remove interference detected by the adaptive notch filter from the data samples.
