ABSTRACT:
A transition-density based data timing measurement method uses an estimated transition density (TD) value for an acquired data signal together with edge crossing times to estimate a data period for the acquired data signal. The estimated data period is used for symbol classification to determine a number of bits between adjacent edge crossings, which results are used to adjust the TD value. The adjusted TD value is then used to re-compute the data period.
