Abstract
A stream of pulses related to rotation rate drives an interrupt to store first timer values of a first timer and to set a second timer to run from zero. At predetermined fixed time intervals, second timer values of the second timer are stored. The stored first timer values are sampled to determine a first rate related to the input stream. The stored second timer values are sampled to determine a second rate. The first and second rates are selectively used as a final rotation rate related to the input stream.
