CALIBRATION METHOD AND CALIBRATION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a method of calibrating a module which is operated based on a module clock signal.

SOLUTION: The method of calibrating the module whose operation is dependent on the module clock signal includes: a step of obtaining over each calibration period of a plurality of such periods, a measure of the frequency of an observed signal, the observed signal being the module clock signal or a clock signal generated based upon the module clock signal; a step of influencing operation of the module in dependence upon the obtained measures to calibrate the module; and a step of taking account of for each calibration period, a position for the end of that calibration period relative to a particular feature of the observed signal and delaying the start of the following calibration period relative to a subsequent particular feature of the observed signal in dependence upon that position.
