| Abstract: | The canonic OC expansion of the first-order Boolean partial derivative of the OC type logic function was discussed. Based on it, the tabular methods calculating the first-order and second-order Boolean partial derivative of the OC type logic function were proposed. According to the definition of the second-order difference and the relation between it and Boolean partial derivative, two tabular methods calculating the second-order Boolean difference of the OC type logic function were presented and compared. These tabular methods proposed in this paper have several advantages such as simplicity, convenience, and is suited to programming on computers. |
