Question
The output signal from an AM modulator is: s(t) = 5cos(1800 t) + 20cos (2000 t) + 5cos (2200 t) (a) Determine the modulation index.
The output signal from an AM modulator is: s(t) = 5cos(1800π t) + 20cos (2000π t) + 5cos (2200π t)
(a) Determine the modulation index.
(b) Determine the ratio of the power in the sidebands to the power in the carrier.
