AM Radio Simulation with audio

AM radio simulation built on AM_radio.m by John Jendzurski

This is a simulation of an AM radio that was derived from AM_radio.m by John Jendzurski. I added the ability to load three MP3 files to setup three "stations" that you can tune to. You can also get a feel for how well the modulation / demodulation preserves the quality of the signal with this example. You will need 3 MP3 or other audio files to run this.
