Information on Quadrature Amplitude Modulation (QAM)

Quadrature amplitude modulation (QAM) is a modulation technique in which both the phase and amplitude of a carrier is varied by the symbols of the message.


Other topics in our resources on Communications Systems related to Quadrature amplitude modulation include: 
 
  • Frequency modulation (FM)
  • Angle modulation
  • Spread spectrum

  • Demodulation
  • Phase modulation (PM)
  • Amplitude-shift keying (ASK)

  • Frequency-shift keying (FSK)
  • Phase-shift keying (PSK)
  • Amplitude modulation (AM)
