What is the approximate bandwidth of a single sideband voice signal?

The approximate bandwidth of a single sideband (SSB) voice signal is around 3 kHz. SSB is a form of amplitude modulation that effectively reduces the bandwidth needed for voice transmission by eliminating one of the sidebands and the carrier frequency. In voice communication, typical SSB transmissions have a modulation frequency range that usually falls within the range of 300 Hz to 3 kHz, covering the essential frequencies for intelligible speech. Thus, when you take into account the necessary bandwidth to transmit these frequencies effectively without distortion, a 3 kHz bandwidth is established as standard for SSB voice signals. This efficient use of bandwidth makes SSB very popular in ham radio and other communication systems, as it allows for clearer signals and effective use of radio spectrum.
