A Magnetostrictive linear position sensor (14) produces a signal which is a time period. It is sometimes required to measure this time period, and provide an output in another form which accurately represents the time period. The final output may be a voltage, current, frequency, digital, or other signal format. A time period is commonly measured using a clock and a counter. The resolution is limited by the frequency of the clock. An upper limit for the clock frequency is usually set based on power consumption, or other circuit constraint. The present invention discloses a method and apparatus (10) for improving the resolution of a time interval while using low power and for providing a response after one time period without averaging. |
