ABSTRACT:
Observation of transient phenomena in an oversampled regime is implemented with a time correction obtained by prepending one or more pseudo datums to the oversampled data to constitute an effective negative delay for the oversampled data set including the pseudo datums. For an oversampling factor N and oversampling rate .omega..sub.s, a digital filter furnishes downsampled data uniformly spaced in time by N/.omega..sub.s and positioned at n (N/.omega..sub.s) where n is the discrete downsampled time coordinate.
