Abstract
In some embodiments an apparatus includes a higher order statistical signal processor to process a jittered digital signal, a diagonal line average unit to identify a distinct line in a signal output from the higher order statistical signal processor, and a peak detection unit to determine a peak value in response to an output of the diagonal line average unit and to provide a data rate signal as an output. Other embodiments are described and claimed.
