Abstract
A distance pulse unit measures the period between valid edges of asymmetrically shaped pulses from a distance pulse sensor. The unit counts individual clock pulse or averages eight individual clock pulses used to determine the period. The averaging occurs if the frequency of the sensor pulses are above a chosen frequency. The averaging aids in reducing the effects of the asymmetry of the sensor pulses.
