20100085890 | REMOVING TIME TAG JITTER AND CROSSOVER DISTORTION - Techniques for removing time tag jitter and crossover distortion from a measurement system are described. A period or clock drift estimate is generated for each sensor, and the estimates are used to remove time tag jitter and detect and remove crossover distortion.
