Physics Course/FM Modulation

Frequency Modulation - FMEdit

In FM Modulation sound wave is mixed with high frequency carrier wave to generate a wave of three frequencies fs - fc , fc and fs + fc. In general , FM wave is not easy to be interfere with other sound waves in the medium travel through therefore the quality of sound is very good . FM sound wave can travel very far . FM wave is usually use to transmit sound through a long distance . FM wave is usually use to transmit sound globally or internationally

 F_s + F_c --> F_s - F_c | F_c | F_s + F_c
