Draw a diagram to show how NAND gates can be combined to obtain an OR gate. (Truth table is not required).

Explanation

To combine NAND gates to obtain an OR gate, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the NAND Gate Functionality**:
- A NAND gate outputs a low signal (0) only when all of its inputs are high (1). In all other cases, it outputs a high signal (1).
- The truth table for a NAND gate is as follows:
- Input (A, B) → Output
