An AM modulator is operating with an index of 0.8. The modulating signal is m(t) = 2

Question:

An AM modulator is operating with an index of 0.8.
The modulating signal is

m(t) = 2 cos(2πf_mt) + cos(4πf_mt) + 2 cos(10πf_mt)

(a) Sketch the spectrum of the modulator output showing the weights of all impulse functions.
(b) What is the efficiency of the modulation process?
