उत्तर
`"Y"_1 = bar"A.A" = bar"A"`
`"Y"_2 = bar"B.B" = bar"B"`
`"Y" = bar("Y"_1."Y"_2) = overline(bar"A".bar"B") = overlineoverline(A) + overlineoverline(B) = "A" + "B"`
The equivalent gate is OR gate
Truth table
| A | B | Y1 | Y2 | Y |
| 0 | 0 | 1 | 1 | 0 |
| 0 | 1 | 1 | 0 | 1 |
| 1 | 0 | 0 | 1 | 1 |
| 1 | 1 | 0 | 0 | 1 |

You are given the two circuits as shown in following figure. Show that circuit
- acts as OR gate while the circuit
- acts as AND gate.
(a)
(b)
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.)
