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 |
