Frequency Modulation (FM) is less affected by noise because the information is carried by variations in the frequency of the carrier rather than its amplitude. Many common types of noise primarily cause unwanted amplitude variations. Since the amplitude of an FM signal remains essentially constant, amplitude-limiting circuits can suppress much of this noise before demodulation, resulting in better signal quality.
An FM signal is less affected by ______.
