प्रश्न
The outputs of two NOT gates are fed to a NOR gate. Draw the logic circuit of the combination of gates. Write its truth table. Identify the gate equivalent to this circuit.
उत्तर
`"Y"_1 = bar"A"`
`"Y"_2 = bar"B"`
`"Y" = overline("Y"_1+"Y"_2) = overline(bar"A"+bar"B") = underset(A)(=) underset(B)(=) = "A.B"`
he equivalent gate is AND gate
