The great advantage of FM is found in how it is received. An FM receiver demodulates a signal by looking for frequency shifts. Most of the noise in our environment is not frequency modulated. So, the FM receiver extracts the information from the FM signal and, by default, leaves out most (or all) of the noise. The result is a clean signal
