Known Quantities: Logical expression for y.

Find: Realization of y using only NAND and NOR gates.

Assumptions: Consider two-input functions and gates.

Analysis: On the basis of the two preceding examples, we see that we can realize the term Z=\overline{(A \cdot B)} using a two-input NAND gate, and the term \overline{Z+C} using a two-input NOR gate. The solution is shown in Figure 13.26.
