Two NOT gates are connected to the inputs of a NOR gate. The given electrical network is equivalent to:

Solution & Step-by-step Explanation

Inputs to NOR gate are \overset{ˉ}{A} and \overset{ˉ}{B} .Output Y = \overline{\overset{ˉ}{A} + \overset{ˉ}{B}} According to De Morgan's Law: \overline{X + Y} = \overset{ˉ}{X} \cdot \overset{ˉ}{Y} $ Y = \overset{ˉ}{\overset{ˉ}{A}} \cdot \overset{ˉ}{\overset{ˉ}{B}} = A \cdot B $ This is the Boolean expression for an AND gate.

Try it yourself before checking the explanation above.
