What is the difference between AM and FM radio and why is FM more popular?
In: Technology
Amplification modulation and frequency modulation are AM and FM.
You can turn a radio wave on and off to represent 1 and 0, but that’s slow with noisy data. What if, instead, you kept it on and ‘pulsed’ the wave? You could change either the frequency or the amplitude of the wave very slightly for a very short period of time. The faster you can ‘pulse’ info onto this wave, the faster you can send data.
