Information on Double sideband

The power consumed in an AM carrier transmits no information and is effectively wasted. It would make sense, therefore, to transmit only the sidefrequencies, which do contain the information. When both sidebands of an AM modulated carrier are transmitted without the carrier, the transmission is called double-sideband suppressed-carrier (DSBSC) or, more commonly, DSB.


Other topics in our resources on Communications Systems related to Double sideband include: 
 
  • Amplitude modulation (AM)
  • frequency modulation (FM)
  • phase modulation (PM)
    		•
  • single sideband (SSB)
  • independent sideband (ISB)
    		•
  • upper sideband (USB)
  • lower sideband (LSB)
