The signal in Figure 3.20 is the output of an AM transmitter with a carrier frequency of 12 MHz and a carrier power of 150 W.
(a) Calculate the percent modulation.
(b) Calculate the RMS voltage of the carrier and use it to find the transmitter's load resistance.
(c) Sketch the signal in the frequency domain, with power in dBm on the vertical axis.
