Identify the correct truth table of the given logic circuit.
| A | B | Y |
|---|---|---|
| 0 | 0 | 1 |
| 0 | 1 | 0 |
| 1 | 0 | 1 |
| 1 | 1 | 0 |
The given logic circuit consists of a combination of logic gates, namely OR, NOT, and AND gates. Let's analyze the circuit step by step to construct the truth table.
- Identify the gates and their functions in the circuit:
- The first gate is an OR gate that takes inputs A and B.
- The second gate is a NOT gate that takes input B and produces \(\overline{B}\).
- The third gate is an AND gate that takes the output of the NOT gate (\(\overline{B}\)) and input A.
- The final gate is another OR gate that takes inputs from both the initial OR gate and the second AND gate.
- Construct the truth table for all combinations of A and B:
| A | B | OR(A, B) | NOT B | AND(A, NOT B) | Final Output Y |
|---|---|---|---|---|---|
| 0 | 0 | 0 | 1 | 0 | 1 |
| 0 | 1 | 1 | 0 | 0 | 1 |
| 1 | 0 | 1 | 1 | 1 | 1 |
| 1 | 1 | 1 | 0 | 0 | 1 |
From the truth table, the key observations are as follows:
- For input combinations where both A and B are not true, the output Y is 1 (i.e., when A = 0, B = 0).
- For other combinations, where at least one input is 1, the output Y becomes 1 based on the OR operation of the initial OR gate and the result from the AND gate using NOT B.
The correct truth table is therefore:
| A | B | Y |
|---|---|---|
| 0 | 0 | 1 |
| 0 | 1 | 0 |
| 1 | 0 | 1 |
| 1 | 1 | 0 |
Thus, the correct truth table is identified as the third option provided.
