An FM transmitter delivers 80W to a load of 30 W when no modulation is present. The carrier is now frequency modulated by a single sinusoidal signal and the peak frequency deviation is so adjusted to make the amplitude of the second sideband is zero in the given output.
J₀(0, 0) = 1,
J₀(2, 4) = 0,
J₀(3.8) = - 0.4,
J₀(5.1)= - 0.1
J₁(2, 4) = 0.52,
J₁((3.8) = 0,
J₁(5.1) = - 0.33,
J₂(2.4) = 0.1
J₂(3.8)= 0.41,
J₂(5.1) = 0
Power in the first order sidebands is :
