Veich diagram
A means of representing Boolean functions in which the number of variables deter mines the number of squares in the diagram; the number of squares needed is the number of possible states, that is, two, raised to a power determined by the number of variables.; 一種用矩形圖來表示布爾函數的方法,在這種方法中變量的個數決定了圖中劃分成方格的個 數,所需方格個數就是可能的狀態數,也就是以變量個數為冪的2的方冪。參閱Venn diagram。
