This assignment deals with minterms, Maxterms, Nands and Nors.

Problem #1

Question 1
Is the gate below a universal gate? It is an AND gate that inverts its input. If a and b are on the other side of the left red wires, the output will be not a and not b.

Make sure you explain why this gate is, or is not, a universal gate. A yes or no answer will not get any credit!

Problem #2

Question 1

Implement the circuit of Homework #1 with NANDs only. One way to do so is to figure out a way to rewrite the expression for the circuit is such a way that it is a combination of terms of the form not( X and Y ).

Question 1
What is the function Q( A, B, C ) implemented by the circuit shown above, where the gates are NAND gates ?
Question 2
What is the diagram of Q using only NOT, OR, and AND gates?
Question 3
What is the minterm canonical form of Q?
Question 4
What is its Maxterm canonical form?
