A wave has 3 parameters Amplitude, Phase, and Frequency. Thus there are 3 types of modulation techniques.
  • Amplitude Modulation: The amplitude of the carrier is varied according to the message signal.
  • Frequency Modulation: The frequency of the carrier is varied according to the message signal.
  • Phase Modulation: The Phase of the carrier is varied according to the message signal.
