Question: Assume that a pure sinusoidal signal given by m(t) = a cos(2fm) modulates a carrier signal A Cos(2fet) in a conventional AM modulation scheme,
Assume that a pure sinusoidal signal given by m(t) = a cos(2fm) modulates a carrier signal A Cos(2fet) in a conventional AM modulation scheme, where the transmitted signal is given by: u(t) = (Ac + m(t)). Cos (2nfet), and fc fm. If the modulation index is given as =0.25; a. What is the power carried in the sidebands (P)? (5 points). b. What is total power (Pt= P + Ps), where Pe is the carrier power? (5 points). c. What is the power efficiency (n= x % 100) of this system? (5 points). Ps Pt
