Compared with amplitude modulation, what are the advantages of FM?

2) High power utilization of the transmitter (power is limited by the ability of the transmitting tube);

3) Good quality of the transmitted signal, large dynamic range;

4) Avoiding large ASK technologyMost noise problems can ignore voltage spikes.In data communication, 2FSK is widely used, and the International Telecommunication Union (ITU) recommends adopting the 2FSK system when the data rate is lower than 1 200b/s.
