| Which of the following statement is true?
A. Any logic expression can be implemented using only NAND gates
B. Any logic expression can be implemented using only NOT gates
C. Any logic expression can be implemented using only EXNOR gates
D. Any logic expression can be implemented using only XOR gates
Please scroll down to see the correct answer and solution guide.
Right Answer is: A
SOLUTION
Concept:
Using NAND gates, we can construct AND gate and NOT so we can say that NAND gate has the property of functionally complete.
Explanation:
NOT gate using NAND gate:
Q = A̅
AND gate using NAND gate:
\({\rm{Q}} = \overline {\overline {{\rm{A}}.{\rm{B}}} } = {\rm{A\;}}.{\rm{B}}\)
Conclusion:
NAND and NOR gate has the property of functionally complete so any logic expression can be implemented using only NAND gate or NOR gate.
