The logic gate equivalent to the given logic circuit is:

The logic gate equivalent to the given logic circuit is:
The logic gate equivalent to the given logic circuit is:

Options

  1. ANAND
  2. BAND
  3. CNOR
  4. DOR

Correct answer

D. OR

Step-by-step solution

From the diagram,
y = \overset{____}{\overset{-}{A} . \overset{-}{B}}
From De Morgan’s law,
y=A−−+B−−y = \overset{-}{\overset{-}{A}} + \overset{-}{\overset{-}{B}}
=A+B= A + B
∴∴ Given circuit represents ‘OR’ gate
