Which of the following statements is true of single sideband (SSB)?
Only one sideband and the carrier are transmitted; the other sideband is suppressed
Only one sideband is transmitted; the other sideband and carrier are suppressed✓پاسخ درست
SSB is the only voice mode authorized on the 20-, 15-, and 10-meter amateur bands
SSB is the only voice mode authorized on the 160-, 75-, and 40-meter amateur bands
توضیح
In SSB, both the carrier and one RF sideband are suppressed, leaving only the other sideband to carry the voice; the two sidebands of an AM signal contain duplicate information, so discarding one loses no message content. Transmitting the carrier would describe a reduced-carrier AM signal, and SSB is not the only voice mode authorized on any amateur band.
