I'm afraid that I'm not going to get this the first time, but here goes:
Say you've got an FM signal. The only thing that varies in an FM signal is the frequency (right?). There are two things that make up an audio signal, frequency and amplitude (how loud the sound is). How is this reproduced in an FM signal, since the only thing that is varying is the frequency? Also, how does it work in an AM signal, since the only thing varying is the amplitude?
