1.	The following configuration of gates is equivalent toA. `HAND`B. `XOR`C. `OR`D. None of these
Answer» Correct Answer - A Output of `G_(1)+A+B` Output of `G_(1)=bar(A.B)` Output of `G_(3)` `=(A+B).bar(A.B)=(A+B).(bar(A)+bar(B))` If `A=1` and `B=1`, then `A+B=1` `A+B=0` So, output is zero, If `A=0` and `B=0`, then `A+B=0` `bar(A)+bar(B)=1+1=1` So, output is zero. Clearly, the given combination is `XOR` gate.
