A combinational logic circuit is shown in Figure 2. [a] Write a general Boolean algebra expression for the output F as a function of the inputs A, B. [b] Using DeMorgan's theorems and other Boolean identities, simplify the expression obtained in [aj. Is there a single gate which can replace the network shown? [c] Generate a truth table giving the logic levels at points C, D, E and F for inputs A,B Part II Design a 2-input exclusive or (EOR) gate using only 2-input NOR gates. [d] Develop the truth table for the gate. [e] Write a general Boolean algebra expression for the output as a function of the inputs. [f] Using DeMorgan's theorems and other Boolean identities, modify the expression obtained in [e] to provide a solution which can be implemented with NOR gates. [g] Draw the circuit diagram for the final gate array. Figure 2 Combinational Logic Circuit
