Which of the following statements about SSB voice transmissions is correct?

The correct statement regarding SSB (Single Sideband) voice transmissions is that they normally use J3E emissions, which consist of one sideband and a suppressed carrier. In SSB modulation, one of the sidebands (either the upper or the lower) is transmitted while the carrier is suppressed, which results in a more efficient use of the available bandwidth. This technique effectively reduces the power required for transmission and allows for clearer audio transmission over longer distances compared to conventional AM, which transmits both sidebands along with the carrier.

Using J3E emissions is advantageous because it helps to enhance the signal-to-noise ratio, making SSB preferred for long-distance communications, especially in amateur radio and other two-way radio operations.

In contrast, the other choices don't accurately represent how SSB operates. AM modulation, as mentioned in one option, refers to amplitude modulation, which transmits both sidebands and the carrier, making it less efficient than SSB. Another option suggests that multiple sidebands are used, which contradicts the fundamental principle of SSB, where only one sideband is transmitted. Lastly, while SSB can operate at lower frequencies, it is not limited to that and can be used effectively across a wide range of frequencies, which
