What is ssb meaning?

SSB stands for Single Side Band modulation. It is a radio transmission technique that allows for more efficient use of the radio frequency spectrum by suppressing one of the two sidebands of a conventional AM modulation signal.

SSB signals occupy only half of the bandwidth required for AM signals, making it possible to accommodate multiple stations within the same frequency band. SSB technology is commonly used in amateur radio equipment, military communications, and some commercial radio services.

In SSB transmission, a carrier signal is modulated by the audio signal, and then one of the two sidebands is suppressed. This causes the received signal to have a much narrower bandwidth, and improved signal-to-noise ratio, enabling better audio quality and greater range.

SSB technology is preferred over AM modulation in long-distance communications due to its narrower bandwidth and improved signal-to-noise ratio, which results in a higher quality audio signal, especially in the presence of interference.
