NBFM Figure 4(b) is a diagram of a commercial FM transmitter using Armstrong's method. Evaluate the multiplier value that applied to the FM transmitter system where the final output that is required to have a carrier frequency of fc4-450 MHz and Af4= 225 kHz. Next, determine the final modulation index value before transmitting if given the sideband voltage, Vm is 0.045 V and carrier input voltage, Ve is 27V.
