Question 188 of 209

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

Show answer and solution

Answer: (D) A−∙B−A^{-}∙B^{-}

First part of figure shown is OR gate and
Second part of figure shown is NOT gate
So YP=OR+NOT=NORgate{Y}_{P}=OR+NOT=NORgate
Y=A+Bˉ=Aˉ.BˉY=\bar{A+B}=\bar{A}.\bar{B}
