What is the approximate bandwidth of a typical single sideband (SSB) voice signal?
- A.1 kHz
- B.3 kHz (correct answer)
- C.6 kHz
- D.15 kHz
WhyA typical single sideband (SSB) voice signal has an approximate bandwidth of 3 kHz. A typical SSB voice signal occupies about 3 kHz of bandwidth, just enough to carry intelligible speech, answer B. 1 kHz (A) would clip too much voice content, and 6 kHz and 15 kHz (C, D) are considerably wider than SSB actually needs.
