What Actually IS the Difference Between AM and FM Radio?

WebAM and FM are the modulation techniques. The prior difference between AM and FM is that in AM the frequency is kept constant and amplitude of the signal changes while in FM the amplitude of the signal is not … Web6 rows · Difference between AM and FM Amplitude modulation and frequency modulation are used to transmit ... Web9. Firstly, FM is a constant-envelope modulation, meaning the amplitude is constant. SSB, being a kind of amplitude modulation, obviously does not have a constant amplitude. Consequently, FM can employ a non-linear amplifier which is more power efficient, and thus has a longer battery life in mobile operation. heltec cloud server
