Fm signal meaning
WebJan 28, 2024 · FM radio operates in the 87.5 MHz to 108.0 MHz range, a higher frequency range than AM radio. The distance range for FM transmissions is more limited than AM, usually less than 100 miles. However, FM radio is better suited for music. The higher bandwidth range of 30 Hz to 15 kHz produces the sound quality we enjoy and prefer.

WebFM is less susceptible than AM to certain kinds of interference, such as that caused by thunderstorms and by random electrical currents from machinery and other related sources. These noise-producing signals affect the amplitude of a radio wave but not its frequency, and so an FM signal remains virtually unchanged.
