Modulation methods used for R.F. telemetry are as follows:

  • Amplitude Modulation
  • Frequency modulation

Amplitude Modulation: The amplitude of the carrier signal is varied continuously according to the instantaneous value of the modulation signal keeping frequency and phase constant.

Let the carrier signal and modulating signal are given as follows

Carrier …
