Consider the following logic circuit. The output is Y =0 when :
Options
- AA =1 and B =1
- BA =0 and B =1
- CA =1 and B =0
- DA =0 and B =0
Correct answer
A. A =1 and B =1
Step-by-step solution
aligned & Y ₁= A ~B , Y ₂= A + B & Y = Y ₁ Y ₂ = Y ₁+ Y ₂ & Y = A ~B + A + B & Y = A + B + A ~B aligned array |c|c|c| A & B & Y 0 & 0 & 1 1 & 0 & 1 0 & 1 & 1 1 & 1 & 0 array
