(Multilevel Logic) Reverse engineer the circuit shown in the schematic of Figure 1 in order to derive a two-level realization.

(a) Find the Boolean expression that describes the circuit.

---

(b) Construct the truth table for the function.

---

(c) Write the function in canonical sum-of-products form (little m notation).

---

(d) Simplify the function using K-maps.
