Abstract: PURPOSE: A method for controlling an offset value and a gain value of an A/D converter is provided to extract correctly an offset value and a gain value by using a fuzzy rule. CONSTITUTION: An offset value and a gain value are set as initial values, respectively(S100). An optimum offset value is extracted from an A/D converter by comparing a minimum value of a sampled signal with a previous offset value after the offset value is set up as the initial value(S200). An optimum gain value is extracted from the A/D converter by comparing a maximum value of the sampled signal with a previous gain value after the gain value is set up as the initial value(S300). The extracted offset value is checked and an extracting process of the offset value is finished or repeated(S400). The extracted gain value is checked and an extracting process of the gain value is finished or repeated(S500).
