Title: Blended velocity estimation

Abstract: A system and method for calculating the speed of a moving member having an output device providing an output periodic signal as a function of displacement of the moving member includes measuring a time duration for a plurality of first periodic occurrences of the output periodic signal to occur. A number of second periodic occurrences of the output periodic signal is also counted in a selected time period. A speed of the moving member is calculated as a function of the time duration for the plurality of first periodic occurrences to occur and the number of second periodic occurrences to occur in the selected time period.
