In AM-DSB if the message m(t) = 6 cos(4000t) and the carrier signal c(t) =18 cos(2x105nt). Answer the below questions: a. Write the expression for the signal wave equation (SAM-DSB). b. Calculate the baseband signal bandwidth? Also calculate the modulated signal bandwidth? c. What type of receiver is be used to demodulate the signal m(t)? d. Calculate Total Power Transmitted, upper Sideband Power and the Power Efficiency of this system.(2 Marks) e. If the modulation index for this signal drops by 5%, how would this affect the transmission efficiency?(1 Mark)
