1. A propagation delay compensation circuit comprising:
a first circuit configured to receive a digital input comprising a measured angular position and to filter noise of the digital input then calculate a speed from a difference in time of a previous angular position and a filtered digital input comprising the measured angular position;
a second circuit configured to receive the speed, and to filter noise from the speed then calculate an acceleration from a difference in time of a previous speed and a filtered speed; and
a third circuit configured to receive the acceleration, the filtered digital input, and the filtered speed and to filter noise of the acceleration then calculate a propagation delay compensated digital output using a filtered acceleration, the filtered digital input, and the filtered speed.
