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(2πfmt) + cos(4πfmt) + 2 cos(10πfmt)
(a) Sketch the spectrum of the modulator output showing the weights of all impulse functions.
(b) What is the efficiency of the modulation process?
