Abstract
An apparatus for calibrating a noise predictive filter includes a noise-predictive filter operable to filter digital data samples to yield filtered data samples, a calibration circuit operable to calculate tap coefficients for the noise-predictive filter based at least in part on the digital data samples, and a gating circuit operable to select a portion of the digital data samples for use by the calibration circuit in calculating the tap coefficients.
