    phase modulation

    noun

    • 1. variation of the phase of a radio or other wave as a means of carrying information such as an audio signal.
  2. Definition: Phase modulation is another type of angle modulation in which the phase of the carrier wave is changed according to the amplitude (magnitude) of the message (modulating) signal. In phase modulation of an analog signal, the phase change is a continuous back and forth movement.

  3. Phase modulation (PM) is a modulation pattern for conditioning communication signals for transmission. It encodes a message signal as variations in the instantaneous phase of a carrier wave. Phase modulation is one of the two principal forms of angle modulation, together with frequency modulation.

  4. Sep 19, 2024 · What is Phase Modulation? Phase modulation (PM) is a kind of signal modulation in which the phase of a high-frequency signal or carrier wave is made to change with its amplitude in proportion to the amplitude of the input signal. This technique modulates information by changing the phase angle of the carrier signal, not its amplitude like the ...

  5. With phase modulation, the slope of the baseband signal governs how quickly the phase changes, and the rate at which the phase changes is equivalent to frequency. So in a PM waveform, high baseband slope corresponds to high frequency, and low baseband slope corresponds to low frequency.

  6. Apr 9, 2020 · What is Phase Modulation? Derivation: PM is a type of angle modulation and it is defined as the change in phase of the carrier signal in correspondence with the amplitude of the message signal. Here, both the frequency and amplitude of the carrier signal stays as constant whereas phase varies in accordance.

  7. Jun 1, 2023 · Phase modulation (PM) is a modulation technique that is widely used in various communication systems to transmit information over a carrier wave by varying the phase of the carrier signal. It is one of the fundamental modulation techniques alongside amplitude modulation (AM) and frequency modulation (FM).
