                      AM                                                                                              FM

1. Poor sound quality                                                                               better sound quality

2. 535 kHz to 1705 kHz                                                                           88 MHz to 108 MHz

3. information stored in amplitude                                                            information is varying frequency

4. affect by noise more                                                                          less affected by noise
