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.
