**Solving Hazards with Redundant Sum Terms**

To address signal hazards in digital logic design, redundant sum terms can be strategically added. Consider the following logic function:

\[ F = (B + D)(A + \overline{C} + D)(A + \overline{B} + \overline{D}) \]

**Understanding the Components:**

1. **Terms and Variables:**
   - \( B, D, A, \overline{C}, \overline{B}, \overline{D} \) are variables or their complements.
   - The expression contains three sets of terms combined using OR and AND operations.

2. **Objective:**
   - To add redundant terms that do not change the logical outcome but eliminate transitional glitches known as hazards.

**Approach:**

- Identify points where the output might change unexpectedly due to race conditions.
- Introduce additional terms to ensure smoother transitions across all input changes, thereby stabilizing the output.

By carefully adding specific redundant terms tailored to the circuit, we can effectively mitigate hazards and improve circuit reliability.
