Advantages

FM is less susceptible to noise and interference than AM because the FM signal is a higher frequency than the AM signal. This means that the FM signal is less likely to be affected by electrical noise and other types of interference.

Reduced background noise: FM signals experience less background noise compared to AM signals, resulting in a cleaner and clearer sound quality, particularly noticeable in areas with electrical interference.
Improved reception in weak signal areas: FM signals can travel farther and penetrate obstacles better than AM signals, making it more reliable in areas with weak or obstructed reception.
Less prone to fading: FM signals are less susceptible to fading caused by atmospheric conditions or obstacles, ensuring a more consistent and stable reception.
Higher fidelity: FM's wider frequency range allows for a wider range of audio frequencies to be transmitted, resulting in higher fidelity and more accurate sound reproduction.

The reduced susceptibility of FM to noise and interference makes it an ideal choice for applications where high-quality audio transmission is crucial, such as in high-fidelity music broadcasting, radio communications, and mobile audio devices.

Disadvantages

The wider bandwidth requirement of FM compared to AM stems from the nature of FM modulation. In FM, the frequency of the carrier wave is varied in proportion to the amplitude of the modulating signal. This variation in frequency necessitates a wider bandwidth to accommodate the range of frequencies used.

The wider bandwidth requirement of FM has implications in various aspects:

Spectrum allocation: FM broadcasting requires a wider portion of the radio spectrum compared to AM broadcasting, which can lead to limitations and competition for spectrum resources.
Transmitter and receiver design: FM transmitters and receivers must be designed to handle the wider bandwidth, which can increase the complexity and cost of these components.
Multipath interference: The wider bandwidth of FM signals makes them more susceptible to multipath interference, where the signal arrives at the receiver via multiple paths, causing distortions and signal degradation.

Despite the wider bandwidth requirement, FM offers significant advantages in terms of noise immunity and audio quality, making it the preferred choice for high-fidelity audio transmission and applications where clear and reliable reception is paramount.
