Physics Course/FM Modulation

Frequency Modulation - FM

In FM Modulation sound wave is mixed with high frequency carrier wave to generate a wave of three frequencies f_s - f_c , f_c and f_s + f_c. 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

$F_{s}+F_{c}-->F_{s}-F_{c}|F_{c}|F_{s}+F_{c}$
