Description: Identify the logic gate given in the circuit:

Solution

$$A$$ after NOT gate is $$ \overline{A} $$.

$$B$$ after NOT gate is $$ \overline{B} $$.

$$ \overline{A} $$ and $$ \overline{B} $$ are inputs to the NAND gate.

$$ Y = \overline{ \overline{A} \cdot \overline{B} } $$

Using De Morgan's law:

$$ Y = A + B $$

i.e., it is an OR gate.
