Information on AM

AM is the form of modulation in which information is impressed onto a carrier wave whose amplitude is caused to vary in accordance with the modulating signal. The types of AM are:
    

  • double sideband

    •     
  • single sideband
  • upper sideband
  • lower sideband

    •     
  • independent sideband.


    • Other topics in our resources on Communications Systems related to AM include: 
     
  • Independent sideband (ISB)
  • Frequency modulation (FM)
  • Angle modulation
  • Spread spectrum
    		•
  • Demodulation
  • Phase modulation (PM)
  • Amplitude-shift keying (ASK)
  • Frequency-shift keying (FSK)
    		•
  • Quadrature AM (QAM)
  • Phase-shift keying (PSK)
  • Double sideband (DSB)
  • Single sideband (SSB)
