What is the value of carrier frequency in the following equation for the FM signal? v(t)= 5 cos(6600t+ 12sin2500t) a. 1150 Hz b. 6600 Hz c. 2500 Hzd. 1050 Hz

Answer»

d. 1050 Hz

A standard FM signal is represented by

v(t) = Ac cos(2πfct + kfsin2πfmt)

Ac = carrier amplitude

fc = carrier frequency 

kf = modulation index 

fm = modulating frequency 

kf = frequency deviation/modulating frequency 

therefore, fc = 6600/2π = 1050Hz
