SSB (Single Sideband) is relatively new in Citizens Band Communications but has been highly effective
in commercial amateur and military usage for many years. It is a superior means of wire'iess com­
munications allowing transmissions of greater distances with a minimum amount of interférence and
noise.
There are two types of single sideband transmissions, USB (Upper Sideband) and LSB (Lower
Sideband). These might be described as half signais and due to the narrow band-width required, will
travel over greater distances at lower power than ordinary AM signais. Figure 1 below illustrâtes
USB and LSB signais and the reference carrier Une.
