Name the Gate represented by the following circuit. A. `OR` gateB. `XOR` gateC. `AND` gateD. `HAND` gate |
|
Answer» Correct Answer - B Output of `OR` gate is `A+B`. Output of `NAND` gate is `bar(A).bar(B)`. New, `Y=(A+B).bar(A.B)=(A+B).(bar(A)+bar(B))` If `A=1` and `B=1` then `A+B=1` and `bar(A)+bar(B)=0` So, `Y=0` If `A=0` and `B=0`, then `Y=0` If `A=1` and `B=0`, then `A+B` gives `1 bar(A)+bar(B)=1` gives So, `Y=1` If `A=1` and `B=1`, then `Y=1` So, the given combination is `XOR` gate |
