Which is true in a frequency modulated system ?

Which is true in a frequency modulated system ? Correct Answer Variation of carrier amplitude does not affect quality of reception

Frequency Modulation:

  • Frequency Modulation is a modulation in which the frequency of the carrier wave is altered according to the instantaneous amplitude of the modulating signal, keeping phase and amplitude constant.
  • So, the variation in carrier amplitude and carrier phase does not affect the signal in the receiving end.
  • Line of sight (LoS) is a type of propagation that can transmit and receive data only where transmit and receive stations are in view of each other without any sort of an obstacle between them. Eg: FM radio, microwave, and satellite transmission.
  • Frequency Modulation works on the Line of sight propagation.


Types of FM detection:

  • Slope detection
  • Phase-locked loop detection
  • Foster Seeley detection
  • Ratio detector
  • Quadrature detectors.
