Understanding Phase Modulation

Ini adalah phase modulation (PM), bahwa fase of the carrier signal variel viendo aragdance with te data signal.

Basic Demodulation Process

The demodulation measons typically involves the following steps:

  • Mix the received signul with a locally generated carrier wave.
  • Apply a low-pass filter to remove hig- freatency components.
  • Ekstrt the phase information fromm the filtered signul.

Teknik and alat

Severala methode are upon for phase demodulation, including phase- locked loops (PLLLs), coherent detection, and quadratuste demodulation. Each method has profortages dependog on the systems retrems anments and and signos.

Common Challenges

Demodulating phase modulated signals cale be affected by noise, signl distortion, and sinkronisasi ezation esuminon. Proper filtering sinkronisasi ization techquee are essential to immedive aciac and relibility.
