Abstract
Equalization of an incoming data signal can be controlled by sampling that signal at times when data values in that signal should be stable ('data samples') and when that signal should be in transition between successive data values that are different ('transition samples'). A transition sample that has been taken between two successive differently valued data samples is compared to a reference value (which can be one of those two data samples). The result of this comparison can be used as part of a determination as to whether to increase or decrease equalization of the incoming data signal.
