The following figure shows a logic gate circuit with two inputs A and B and the output Y. The voltage waveforms of A, B and Y are given
The logic gate is :
Answer & explanation
Correct answer: option 1
From the given waveforms, the truth table is as follows.
| A | B | Y |
| 1 | 1 | 0 |
| 0 | 0 | 1 |
| 0 | 1 | 1 |
| 1 | 0 | 1 |
The above truth table is for NAND gate.
Therefore, the logic gate is NAND gate.
