单词 phase modulation
释义

Definition of phase modulation in English:

phase modulation

noun
mass nounElectronics
  • Variation of the phase of a radio or other wave as a means of carrying information such as an audio signal.

    〔电子〕相位调制,调相

    Example sentencesExamples
    • Changes in the wavelength for the maximum signal are used to directly determine the spectral phase modulation of the femtosecond pulse.
    • Phase Jitter is the unwanted phase modulation of a primary signal by one or more other signals through the transmission process.
    • The amplitude and phase modulation of the NMR-signal as a function of the displacement encoding steps can be Fourier transformed to obtain the propagator.
    • This rotation can cause amplitude and phase modulation of the GPS signal, reducing navigation performance and effectiveness of traditional anti-jam systems.
    • The system carries out a new phase scan to determine the remaining spectral phase modulation (usually about 10% of the original).
