(Multilevel Logic) Write down the function represented by the circuit network in Figure 1 in a multilevel factored form using AND, OR, and NOT operations only—that is, no NAND or NOR operations.

Derive the simplest Boolean expression you can (minimum number of literals and fewest gates) for the function represented by this schematic. You may use any kind of logic operators described in this chapter.
