Draw the logic gate symbol for a 4-input AND gate. Write the Boolean function and truth table. [20] Deduce the Right-hand side of three variable DeMorgan's theorem shown below using Boolean axioms and theorems. You must show all steps and identify the axiom/theorem used for simplification. [20] (x+y+z)' = How many rows does the truth table of a N-input AND gate have? Justify your answer. [10]
