Consider the message signal: m(t) = 20 cos (2*pi*t) volts
and the carrier wave: c(t) = 50 cost(100*pi*t) volts
a. Sketch (to scale) the resulting AM wave for 75% of the modulation
b. Find the power developed across a load of 100 ohms due to this AM wave.
This solution contains stepwise calculations and explanations using MATLAB to sketch the resulting AM wave and also finding the power developed across a load of 100 ohms.
