What Does USB Stand For?
USB stands for Upper Side Band
USB, or Upper Side Band, is a method of amplitude modulation used in telecommunications, particularly in radio transmission. It involves the transmission of audio signals by modulating the upper frequency side of a carrier wave, allowing for more efficient use of bandwidth and reduced interference from adjacent frequencies. USB is commonly utilized in single-sideband (SSB) radio operations, providing enhanced clarity and range for voice communications, particularly in amateur and maritime radio.
