![### Digital Logic Design Exercise
**Objective:**
Design a digital circuit using only NOR gates to implement the following Boolean expression:
\[ Y = (a + b)(c + d) \]
**Instructions:**
1. **Understand NOR Gate Functionality:**
- The NOR gate is a universal gate. It performs the logical NOR operation, which is the negation of the OR operation.
2. **Convert the Expression:**
- Use De Morgan’s Theorems and other logic transformations to convert the given expression into a form that employs only NOR gates.
3. **Design the Circuit:**
- Draw the logic circuit diagram using only NOR gates based on your transformation of the original expression.
**Tips:**
- Recall that any Boolean function can be implemented using just NOR gates.
- The NOR gate is equivalent to an OR gate followed by a NOT gate.
- Apply the double inversion technique to mimic AND and OR functionalities using NOR gates.
**Example Techniques:**
- \[(a + b)'\] can be represented using a single NOR gate.
- \[(a \cdot b) = ((a' + b')')\], allowing AND implementation through NOR.
**Practice:**
Try drawing the circuit on paper or using a digital circuit design tool to verify its operation.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F39c6e25e-d467-4ba4-a648-1f12925c88db%2F25c14546-2369-43bc-81cc-341e57ab4744%2F6hyya2n_processed.png&w=3840&q=75)
