Problem 12
Inverting the output of an AND gate is equivalent to inverting the individual signals first, then passing them through an OR gate.
Problem 20
Produces a 0 only if all its inputs are 0 and a 1 otherwise.
Problem 31
Distinguish between a gate and a circuit.
Problem 32
What are the three notational methods for describing the behavior of gates and circuits?
Problem 36
Give the three representations of a NOT gate and say in words what NOT means.
Problem 39
Give the three representations of an XOR gate and say in words what XOR means.
Problem 40
Give the three representations of a NAND gate and say in words what NAND means.
Problem 41
Give the three representations of a NOR gate and say in words what NOR means.
Problem 42
Compare and contrast the AND gate and the NAND gate.
Problem 43
Give the Boolean expression for a three-input AND gate, and then show its behavior with a truth table.
