摘要:
The present subject matter relates to methodologies for providing error correction compensation to measurement systems. Data-dependant jitter may be compensated by examining both short-term and long-term bit histories after applying a predetermined synthesized calibration pattern having selected characteristics to the measurement system. Neural networks may be provided to produce error correction signals that may be applied to measured data on a bit-by-bit basis to correct jitter. The synthesized calibration sequence may correspond to a base pattern having two segments; a first segment may correspond to a copy of the base pattern while the second segment may be a copy of the base pattern with some sections inverted.
