What does the term splatter describe?

  • A.Impulse noise from ignition systems
  • B.Fading of one sideband relative to the other
  • C.Distortion produced by a long detector time constant
  • D.Spectral spreading caused by over-modulation

Answer: D

Splatter is the energy that appears outside the assigned channel when a transmitter is over-modulated or its audio is clipped, and it is heard by listeners tuned to neighbouring channels rather than by the offending station's own audience. Ignition noise is an external interference. Selective fading is a propagation effect. And distortion from a long detector time constant is diagonal clipping, which is a receiver fault confined to that receiver.
