Abstract
A technique for filter-enhanced clock synchronization is disclosed. In one particular exemplary embodiment, the technique may be realized by/as a method for filter-enhanced clock synchronization. The method comprises subjecting a clock error signal to a first exponentially weighted moving average (EWMA) filter to generate a first output signal, where the first EWMA filter comprises a first gain element. And the method further comprises subjecting the first output signal to a second EWMA filter to generate a second output signal, where the second EWMA filter comprises a second gain element and the second EWMA filter is coupled with a feedback loop having a delay element and a summing junction.
