An AM transmitter supplies 10 kW of carrier power to a 50 load. It operates at a carrier frequency of 1.2 MHz and is 80% modulated by a 3 kHz sine wave.
(a) Sketch the signal in the frequency domain, with frequency and power scales. Show the power in dBW. (If necessary, refer to the discussion of dBW in Appendix A.)
(b) Calculate the total average power in the signal, in watts and dBW.
(c) Calculate the RMS voltage of the signal.
(d) Calculate the peak voltage of the signal.
