Which property of a signal does its phase spectrum carry?

  • A.The bandwidth the signal occupies
  • B.The signal-to-noise ratio at the receiver input
  • C.The relative timing of its frequency components
  • D.The total power contained in the signal

Answer: C

Phase encodes when each component peaks relative to the others, and it is what determines the waveform's shape: two signals with identical amplitude spectra and different phase spectra look completely different in time. Power comes from the amplitude spectrum through Parseval. Bandwidth is the extent of the amplitude spectrum. And signal-to-noise ratio depends on the channel and the receiver rather than on any property of the signal alone.
