Figure 3: Curves of for different combination of and in (2.1). (a) . The inputs can be shown by a curve, and the inputs , , and can be shown by other different curves, respectively. (b) . The inputs can be shown by one curve, and the inputs , , and can be shown by other different curves, respectively. (c) . The inputs can be shown by one curve, and for the inputs , , and can be shown by other different curves, respectively. (d) . The inputs can be shown by one curve, and the inputs , , , and can be shown by other different curves, respectively. Different logic functions can be obtained from Figures 3(a), 3(b), 3(c) and 3(d) with the same and .
