प्रश्न
You are given circuit as shown in the figure, which consists of NAND gate. Identify the logic operation carried out by the two. Write the truth table. Identify the gates equivalent to the tow circuits.
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 |
