Abstract:
A system for measuring the time interval of a signal. The second signal has a frequency higher than a frequency of the first signal. According to one embodiment, the system includes an electronic circuit for determining an approximation of the time based on a period of the second signal and for determining an adjustment to the approximation based on the second signal and a third signal corresponding to the second signal and aligned with the first signal. The length of the adjustment is less than the period of the second signal.
