For the given digital circuit, write the truth table and identify the logic gate it represents :

Step-by-step solution

The given digital circuit is shown as follows: Using Boolean law: ( A+A=A ), we get ( A+A = A ) and ( B+B = B ) Using de Morgan's theorem: ( A+B = A B ) ( A + B = A B ) and using ( A =A ), we get ( A B =A B ) Therefore, ( Y=A B ) Truth table array |l|l|l|l|l| A & B & A + A & B + B & Y 0 & 0 & 1 & 1 & 0 0 & 1 & 1 & 0 & 0 1 & 0 & 0 & 1 & 0 array
