Question

The symbolic representations of four logic gates are given. The logic symbols for OR, NOT and NAND gates are respectively:

Accepted Answer

To identify the logic gates from their standard symbolic representations:
1. **OR Gate:** Represented by a symbol with a curved input side and a pointed output. Based on the provided correct sequence, this corresponds to (iv).
2. **NOT Gate:** Represented by a triangle with a small bubble (inversion circle) at the output. This corresponds to (ii).
3. **NAND Gate:** Represented by a D-shaped AND gate symbol with a small bubble at the output. This corresponds to (i).
4. **Conclusion:** Therefore, the correct sequence for OR, NOT, and NAND gates is (iv), (ii), and (i) respectively.
