Abstract
A bus data signal is applied to a tapped data delay line. The various increasingly delayed data values present at the taps of the delay line are clocked into respective cells of a sticky ZEROs register (SZERO) previously initialized to all ONES, and into respective cells of a sticky ONES (SONE) register previously initialized to all ZEROS. SZERO measures the unit interval of a ONE.
