Abstract
An embodiment of a technique to determine an expected occurrence of a signal is disclosed. The technique includes receiving first and second signals, and storing delay information representing an expected time delay from an occurrence of the first signal to a point in time corresponding approximately to an expected occurrence of the second signal. The technique further includes responding to an occurrence of the first signal by: waiting for a time interval equivalent to the expected time delay, evaluating the second signal at approximately the end of the time interval, and adjusting the stored delay information if the second signal occurred outside a time window associated with the end of the time interval.
