The logic circuit and its truth table are given, what is the gate X in the diagram |
|
Answer» SOLUTION :From the truth table we not that `Y=A+B` i.e., it is for OR gate (or) `A+X=A+B=A+B.(A+BARA)(because A+barA=1)` then, `A+X=A+B.A+B.barA=A.(1+B)+barA.B=A+barA.B` So `X=barA.B`, which is AND gate with INPUTS as `barA` and B |
