If an RF signal is AM modulated with a analogue signal any noise will add or subtract to the amplitude of the RF signal and will be present in the audio signal after detection, also will the noise add itself to the audio signal, where as in digital communication a slight variation in the amplitude of the signal is of no concern because you only work with ones and zeros, it’s high or it’s low
