The output (Y) of the given logic implementation is similar to the output of an/a _______ gate. [2025]
OR
NOR
AND
NAND
(2)
The output Y for the inputs A and B of the given logic circuit is [2024]
(3)
When the output of an OR gate is applied as input to a NOT gate, then the combination acts as a [2024]
NAND gate
NOR gate
AND gate
OR gate
(2)
For OR gate, Y = A + B
NOT gate is applied to Y,
So, when output of OR gate is applied as input to a NOT gate, then the combination acts as a NOR gate.
A logic circuit provides the output Y as per the following truth table: [2024]
The expression for the output Y is
(3)
Given truth table:
| A | B | Y |
| 0 | 0 | 1 |
| 0 | 1 | 0 |
| 1 | 0 | 1 |
| 1 | 1 | 0 |
The given truth table is satisfied by, the expression,
The output (Y) of the given logic gate is similar to the output of an/a [2024]
NAND gate
NOR gate
OR gate
AND gate
(4)
So, the output Y represents AND gate.
For the following logic circuit, the truth table is [2023]
(4)
Here, NAND gate is followed by two NOT gates.
By using A = 0, B = 0, we get Y = 0
A = 0, B = 1, Y = 1
A = 1, B = 0, Y = 1
A = 1, B = 1, Y = 1
This corresponds to OR gate.
