What does SSB stand for in radio communication?

SSB stands for Single Sideband in radio communication, which is a refinement of amplitude modulation (AM) that more efficiently uses transmitter power and bandwidth. Unlike AM, where both the upper and lower sidebands, as well as a carrier signal, are transmitted, SSB transmits only one of the sidebands (either upper or lower) and omits the carrier. This results in a more efficient use of power and allows for longer-range communication with clearer signals, as it reduces interference and noise.

Single Sideband is widely used in various applications such as amateur radio, maritime communication, and aviation. Its ability to transmit information effectively over long distances makes it a crucial technology in radio communication systems.
