Abstract
A method and system for removing the effect of intersymbol interference (ISI) from a data record indicating times of logic level transitions exhibited by a data signal that has been distorted by ISI exhibited by a system having a particular step response may perform the following acts. The data record may be received, and a transition from within the data may be selected record for removal of ISI. Preceding transitions within the data record are then inspected. A time defect is obtained, based at least in part upon the inspected preceding transitions. Finally, the data record is adjusted, based upon the time defect, to indicate a new time of transition for the selected transition, thereby removing the effect of ISI for the selected transition.
