Question
Identify the equivalent gate for the following circuit and write its truth table.
Solution
Output,`Y=overline(A'+B')`
Here A′ ≡ Output of A from NOT gate, = `overlineA`
B′ ≡ Output of B from NOT gate, = `overlineB`
Thus, Output `Y=overline(A'+B')`
`=overlineA'*overlineB'`
=`A*B`
So, the equivalent gate for the given circuit is AND GATE.
