A logic circuit provides the output Y as per the following truth table :
A | B | Y |
0 0 1 1 |
0 1 0 1 |
1 0 1 0 |
The expression for the output Y is :
A.B + Ā
A.B̅ + Ā
B̅
B
B̅
A | B | Y |
0 0 1 1 |
0 1 0 1 |
1 0 1 0 |
According to given truth table, output is independent on value of A
∴ Output Y = B̅
