Classification: CPC H  G | IPC G  H

Claim 15:
16. A method of calculating propagation delay compensation, the method comprising:
receiving a digital input comprising a measured angular position of a rotating object;
comparing the measured angular position to a previously calculated angular position of the rotating object;
determining the measured angular position is not valid based on the comparing; and
replacing the measured angular position with an extrapolated angular position based on the previously calculated angular position;
calculating a speed from a difference in time of the extrapolated angular position and a previous angular position;
calculating an acceleration using a difference in time of the speed and a previous speed;
receiving the extrapolated angular position, the speed, and the acceleration in a delay compensator; and
calculating, in the delay compensator, a propagation delay compensated digital output.
