Ok A question here about how AM & FM modulation works.
I know that AM trasmits the sound by varying the voltage of the radio signal, and FM varies the frequency itself of the signal, however, viable sound needs two things, varying frequency AND VARYING AMPLITUTE. So the modulation, whether FM or AM, transmits only 1 variation, so it needs to transmit one more for the volume of the sound, how does it transmit that?
Thanks!
