Q.
Choose the correct logic circuit for the given truth table having inputs A and B.
| Inputs | Output | |
|---|---|---|
| A | B | Y |
| 0 | 0 | 0 |
| 0 | 1 | 0 |
| 1 | 0 | 1 |
| 1 | 1 | 1 |
- A
- B
- C
- D
Solution
The truth table shows : the output simply follows input A, regardless of B.
Verifying the four rows: , , , . Each output equals A.
Among the given circuits, only option (2) realises this function. Its structure is , and by absorption , matching the table.
