Question:

Boolean relation at the output stage- $Y$ for the following circuit is:

  1. $\bar{A}+\bar{B}$

  2. $A+B$

  3. $A . B$

  4. $\bar{A} \cdot \bar{B}$


Correct Option: , 4

Solution:

$\mathrm{OR}+\mathrm{NOT} \rightarrow \mathrm{NOR}$ Gate

Hence Boolean relation at the output stage $-Y$ for the circuit,

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