The resultant gate and its Boolean expression for the given circuit is

The resultant gate and its Boolean expression for the given circuit is
  1. OR, $A+B$
  2. $\mathrm{NOR}, \overline{A+B}$
  3. $\quad \mathrm{NAND}, \overline{A \cdot B}$
  4. $\quad A N D, A \cdot B$

Solution

Here a NOR gate is followed by a NOT gate which gives an OR gate which has Boolean expression $A+B$
