Question
QI: Suppose you have the following modulated signal:
ø(t) = 6 cos(1600nt) + 22 cos(1800nt) + 6cos(2000nt)
Сompute:
I- Determine the modulating signal m(t) and the carrier signal c(t).
2- Determine the modulation index m.
3- Determine the ratio of the power in the sidebands to the power in the carrier.
Q2 : Suppose you have the following modulated signal with the output wave
changes of 5.5 V,:
V (1) =15sin(27600x10' )t – 4.25cos(27490x10')t +3.75cos(2r460x10
Сompute:
1- Caleulate the modulation coefficient and percent modulation.
2- Calculate the peak amplitude of the modulated carrier, upper and lower side
frequency voltages.
3- Calculate the maximum and minimum amplitude of the envelope.
4- Draw and label the frequency spectrum.
5- Sketch and label the output envelope.
