Frequency Modulation (FM) is a key technology in the world of radio communications, offering a unique way to modify a carrier signal. Unlike Amplitude Modulation (AM), which alters the signal's strength, FM changes the frequency of the carrier signal based on the modulating signal. This approach provides notable advantages, such as better resistance to noise and interference, but also comes with its own set of challenges.
