FM has superior noise characteristics compared to AM. This is because the amplitude of the FM signal remains constant, while the frequency varies, which means that any noise in the signal only affects the amplitude, not the frequency. Therefore, FM signals are less susceptible to interference from noise and other sources of interference.
