*Question T8A08:
What is the approximate bandwidth of a typical single sideband (SSB) voice signal?*  

*Correct Answer is  B: 3 kHz*  

### AI Response: (may contain errors)  

The approximate bandwidth of a typical single sideband (SSB) voice signal is about 3 kHz. Here's a breakdown of why this is the correct answer and why the other choices are incorrect.

### Correct Answer: 3 kHz
- **Explanation**: SSB is a form of amplitude modulation that uses only one of the sidebands and suppresses the carrier. The bandwidth of an SSB signal is typically around 2.7 kHz to 3 kHz. This bandwidth is sufficient to transmit the human voice clearly, capturing the essential frequencies needed for intelligibility.

### Why Other Choices Are Incorrect:
- **A: 1 kHz**  
  - **Reason**: 1 kHz is too narrow for SSB voice communication. While some digital modes may operate within this bandwidth, SSB requires more bandwidth to accommodate the full range of human speech.

- **C: 6 kHz**  
  - **Reason**: 6 kHz is wider than necessary for SSB voice signals. While some high-fidelity audio transmissions may use this bandwidth, standard SSB voice typically does not require this much.

- **D: 15 kHz**  
  - **Reason**: 15 kHz is excessively wide for SSB voice signals. This bandwidth is more appropriate for wideband FM or high-quality audio transmissions, not for standard SSB voice communication.

### Summary
- The typical bandwidth for SSB voice is approximately 3 kHz, which balances clarity and efficiency in communication. Understanding this bandwidth helps in selecting appropriate filters and equipment for SSB operation.
