Description: Identify the logic operation performed by the given circuit

Solution

$$\text{Output of upper NOR gate} = \overline{A + A} = \bar{A}$$

$$\text{Output of lower NOR gate} = \overline{B + B} = \bar{B}$$

Final output from the rightmost NOR gate: $$Y = \overline{\bar{A} + \bar{B}}$$

Applying De Morgan's law: $$Y = \overline{\overline{A}} \cdot \overline{\overline{B}} = A \cdot B$$
