What is the difference between AM and FM radio and why is FM more popular?
In: Technology
You want to talk to your friend who lives on the other side of a big lake or pond, it’s so big you can’t see him, but fortunately you can control the pattern of the waves and he can read the pattern (convenient!).
So, you and him have two ways to talk.
One. Amplitude modulation. You can send a 2ft wave, then a 5ft wave, then a 3 ft wave and so on, so that he receives the message 253.
Two. Frequency modulation. You send a bunch of 2ft waves, but send them at a varying frequency. So ___2_2___2___. He measures the frequency that the 2ft waves arrive and reads 3133.
The advantage of frequency modulation is that you can send more frequent waves than you can if you have to control the height of each wave.
