ABSTRACT:
A data recovery technique for jitter tolerant peak detected channels. The number of consecutive zeros between ones are reproduced in a run-length coded, peak detected channel. The interval (time, distance) is measured between peaks of a run-length encoded digital data signal wherein peaks represent ones and absence of peaks represent zeros. A look-up-table is provided having entries for all possible intervals between peaks for the run-length code used and corresponding entries for the number of zeros between ones. The measured interval is applied to the look-up-table to produce a string of zero bits between one bits.
