उत्तर

Y1 = Error! Objects cannot be created from editing field codes.
`"Y" = overline((bar"A.B").(bar"A.B")) = overline(bar"A.B").overline(bar"A.B") = ("A.B")+("A.B")`
= `"A"."B"`
The equivalent gate is AND Gate
Truth table
| A | B | Y1 | Y |
| 0 | 0 | 1 | 0 |
| 0 | 1 | 1 | 0 |
| 1 | 0 | 1 | 0 |
| 1 | 1 | 0 | 1 |
