An indirect-FM transmitter has the block diagram shown in Figure 5.37. The total output power is 1 W to 50 .
(a) Label the block that has been left blank.
(b) What phase deviation will be necessary at the modulator in order for the output frequency to deviate by 5 kHz with a 1 kHz modulating signal
(c) Use Bessel functions to sketch the spectrum of the output signal. Be sure to include suitable scales. It is necessary to include only the carrier and the first three sidebands on each side. Figure 5.36
