The above combination of gates produces a

A

AND gate

B

XOR gate

C

NAND gate

D

NOR gate

Text Solution

Verified by Experts


Here `X_(1) = bar(A.B)` and `X_(2) = A+ B`
`=(A+B).bar(A.B) = (A+B) l . (bar(A)+ bar(B))`
`=0 + A bar(B) + B bar(A) + 0 = bar(A) B + A bar(B)`
This is the expression for a XOR gate.
