摘要：
Systems and techniques relating to interpreting signals on a channel having an asymmetrical signal amplitude response include an integrated circuit device including: an input to receive digital data corresponding to an asymmetry corrected analog signal of a read channel; an input to receive sequence data detected in the digital data; circuitry to generate a coefficient adjustment based on an estimate of non-linearity for the read channel, the estimate derived from the digital data and the sequence data; and an output to provide the coefficient adjustment to affect asymmetry correction of the analog signal.
