Fm Stereo; Broadcasting Knowledge; What Kind Of Signal Can Interfere With Fm Broadcasts - Tecsun S-8800 Operation Manual

The figure shows an AM signal that has two sidebands with information, each
a copy of the other, and the carrier wave. To enhance the efficiency of the signal, the
carrier wave and either one of the sidebands can be eliminated. What remains is a
single side band (SSB).
Besides the capability of receiving AM signals, a radio device requires a specific
demodulator to receive the information from SSB signals. The advantage of SSB
transmissions is the narrow bandwidth (gives better selectivity and less noise),
higher power efficiency and longer transmission distance. The disadvantage is that
the sound is slightly distorted, which makes it primarily suitable for less demanding
audio quality communication.
