Which of the following statements is true of single sideband (SSB)?
- A.Only one sideband and the carrier are transmitted; the other sideband is suppressed
- B.Only one sideband is transmitted; the other sideband and carrier are suppressed (correct answer)
- C.SSB is the only voice mode authorized on the 20-, 15-, and 10-meter amateur bands
- D.SSB is the only voice mode authorized on the 160-, 75-, and 40-meter amateur bands
WhyIn single sideband, only one sideband is transmitted; the other sideband and the carrier are both suppressed. SSB transmits exactly one sideband while suppressing both the other sideband and the carrier, which is the whole point of the mode, less bandwidth and no wasted carrier power, answer B. Choice A transmits a carrier along with one sideband, which describes a different, compatible-AM style of operation, not standard SSB, and C and D both overstate SSB's exclusivity, other modes are also authorized on those band segments.
