## 5. Engineering Risks & FAQ
- **Caution**: 
- **Caution**: 
- **Caution**: 

### Q: What makes this a true random number generator compared to pseudo-random generators?
**A**: This hardware TRNG generates numbers from physical processes like thermal noise in resistors, making them fundamentally unpredictable, unlike software-based pseudo-random generators that use deterministic algorithms.

### Q: What are the primary applications for this hardware TRNG?
**A**: It's designed for cryptographic security applications including encryption key generation, secure authentication systems, digital signatures, and any electronic system requiring high-quality, unpredictable random numbers.

### Q: How does the entropy source module ensure randomness?
**A**: The entropy source captures physical phenomena like thermal noise or quantum effects, which are inherently random. This analog signal is then amplified, digitized, and conditioned to produce statistically random digital output.
