Abstract
A technique for converting asymmetric waveforms into symmetric ones. The technique is used in disk drive read channels which receive asymmetric waveforms from magnetoresistive heads. Conversion of these waveforms into symmetric ones results in improved bit error rate of the read channel. The correction technique can be used for any general asymmetry transfer function, and in any general application where the correction of asymmetric waveforms is needed. The technique involves splitting the input signal into two rectified paths and applying correction independently on each of the paths.
