What is an advantage of frequency modulation?

Explanation:
Frequency modulation carries information in changes to the carrier’s frequency rather than its amplitude. Because noise and interference often distort amplitude more than frequency, the FM demodulator can recover the original signal without being as affected by those disturbances. Keeping the carrier’s amplitude constant means amplitude noise doesn’t translate into data errors, so the received signal remains clearer in noisy or interfered environments. That resilience to noise and interference is the key advantage of frequency modulation. (Note the trade-off: FM typically needs more bandwidth and can be more complex to implement.)
