What is the difference between AM and FM radio and why is FM more popular?
In: Technology
Imagine a robot is trying to talk to you use using a bunch of beeping noise. A robot that communicates using FM is changing the pitch of the beep (high pitch or low pitch) to convey information. A robot that communicates using AM is changing the loudness of the beep.
FM is more popular because it has more bandwidth allocated to it – meaning more information can be transmitted to your radio. You can make AM sound better by using a larger bandwidth.
