Question
What is the approximate bandwidth of a typical single sideband (SSB) voice signal?
Answer Options
- A) 1 kHz
- B) 3 kHz
- C) 6 kHz
- D) 15 kHz
Correct Answer: B
Explanation
The bandwidth of an SSB voice signal is determined by the range of audio frequencies being transmitted. To provide acceptable voice quality while maximizing efficiency, amateur radio SSB voice signals typically utilize an audio range of 300\text{ Hz} to 3,000\text{ Hz}.
Therefore, the approximate bandwidth of a typical SSB voice signal is 3\text{ kHz}. This narrow bandwidth is a key reason why SSB is the primary mode for long-distance voice communication on the HF bands.
