The 7 pages that link to Phase modulation, each with the reason it gives.

• Frequency modulationCompared with: PM also changes carrier angle, but directly follows the input signal’s phase-related variation.

• Amplitude modulationCompared with: It changes carrier phase instead of the amplitude varied in AM.

• Signal modulationBroader topic: It conveys information through shifts in the carrier’s phase.

• Analog signalBroader topic: It demonstrates how an analog signal can encode information without changing amplitude.

• Carrier waveBroader topic: It encodes information by changing the carrier’s phase.

• Mach–Zehnder interferometerRelated: A phase modulator in one arm can control the interferometer's output.

• DemodulationRelated: Its encoded phase changes require phase-sensitive recovery.
