A) AND
B) NOT
C) OR
D) NOR
Correct Answer: A
Solution :
Let two inputs are A and B. The circuit can be shown as: The two gates shown are NAND gates. The output of gate \[-1,{{Y}_{1}}=\overline{A.B}\] The output of gate \[-2,Y=\overline{{{Y}_{1}}.{{Y}_{1}}}\] or \[Y=\overline{\overline{A.B}.\overline{A.B}}\] \[=\overline{\overline{A.B}}\] \[=A.B\] Thus, the combination behaves as it is an AND gate.You need to login to perform this action.
