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
Truth table
| A | B | Y1 | Y2 | Y |
| 0 | 0 | 1 | 1 | 0 |
| 0 | 1 | 1 | 0 | 0 |
| 1 | 0 | 0 | 1 | 0 |
| 1 | 1 | 0 | 0 | 1 |

Write the truth table for circuit given in figure below consisting of NOR gates and identify the logic operation (OR, AND, NOT) which this circuit is performing.

(Hint: A = 0, B = 1 then A and B inputs of second NOR gate will be 0 and hence Y=1. Similarly work out the values of Y for other combinations of A and B. Compare with the truth table of OR, AND, NOT gates and find the correct one.)
