Single Side Band Modulation

  • SSB
German: Einseitenband-Modulation
Japanese: 単側波帯変調

Communications engineering. In amplitude modulation the combination of the carrier with the modulation signal results in two sidebands, one above and one under the carrier frequency both containing the same information. If only one of these sidebands is selected by a filter and used for further transmission the technique is called single side band modulation. It needs less transmission capacity than other amplitude modulation techniques. SSB applies to the transmission of long distance phone calls and for voice transmission in amateur radio.
