Which of the following statements is NOT true?
Boolean Algebra is the only way to simplify complex logic expressions.
Boolean Algebra creates simplified expressions that will result in a logic circuit that is equivalent to the original circuit, yet requires fewer gates.
Boolean Algebra provides the ability to algebraically simplify logic expressions.
Boolean Algebra uses many of the normal algebra rules such as commutative, associative and distribution laws.
Choose each statement that is true (there may be more than one): A "Don't Care" condition...
...indicates a condition where the design doesn't care if the output is (0) or a (1).
...can be entered in the K-map anyplace to help simplify the expression.
...can not be used for grouping to create simpler terms.
...is marked by (X) in the truth table
...can be treated as a (0) or a (1) in a K-map.

Which of the following is true (check all that apply)?
When converting a circuit from AOI to NAND or NOR, double inversions (i.e., back to back inverters) can be eliminated.
NAND gates can only be used to replace AND gates
Any combinational logic expression can be implemented using only NAND gates or only NOR gates.
NAND or NOR implementations of a circuit will often reduce the number of integrated circuits (IC) required to implement a logic circuit.
Using only NAND gates will always reduce the number of gates needed to implement a logic circuit
NOR gates can only be used to replace NOR gates
NAND and NOR gates are called universal gates because there is no difference between their truth tables.
