Abstract:
A system and method for measuring frequency which reduces the impact of noise. The system and method includes the steps of sampling a signal train over a first signal portion of the signal train, determining a first average period for the first signal portion (t1) of the signal train, sampling the signal train over a second signal portion (t2) of the signal train, wherein, the second portion of the signal train overlaps with the first signal portion, determining a second average period for the second signal portion (t2) of the output signal train, and then determining the average of the determined average periods.
