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.J(0, 0) = 1, J(2, 4) = 0, J(3.8) = - 0.4, J(5.1)= - 0.1J(2, 4) = 0.52, J((3.8) = 0, J(5.1) = - 0.33, J(2.4) = 0.1J(3.8)= 0.41, J(5.1) = 0Power in the first order sidebands is : |
| Answer» Power in first order side bands = 2(J1(β))2 x 100 = 21.78 W. | |
