摘要

method and apparatus for determining a representative measurement which is indicative'be a relative oscillation speed of a reference clock over a representative calibration period; and apparatus for determining a measured number of cycles of a reference clock signal that occurs during a representative calibration period shall be determined.a representative measurement indicating a relative oscillation speed of a reference clock over a representative calibration period. Multiple.calibration periods are defined,including first and second calibration periods. the first calibration period starts at the first moment of departure, where a first time deviation value is equal to a difference between the first moment of departure and a point of transition of the reference clock signal within the first calibration period. The second calibration period shall begin at a second starting point,where a second time deviation value is equal to a difference between the second departure moment and a transition point of the reference clock signal within the second calibration period. the first and second time deviation values are different from each other. Measurements are generated for each of the calibration periods by measuring the speed of the reference clock. the measurements are then submitted to mean.
