Problem No. 1: Let us consider that a baseband message signal m(t)=4cos(2000xt) has to be transmitted from a location 'A' to its destination 'B' using a carrier signal given by c(t)=2cos(10000#t). The signal s() m(t)c(i) is the modulated signal which will be transmitted. Consider that the signal is transmitted through a noiseless channel and received at the receiver at location 'B' as the signal s(t). Based on this information, perform the following tasks. 1. Find, sketch and label the spectrum...

Consider the message signal m(t):
Consider the message signal m(t):a. Sketch the AM signal u(t)=[ A + m(t) ] Cos(wct) for modulation indexes μ = 0.5 and μ = 2.0 by assuming the carrier frequency to be much higher than the bandwidth of m(t) b. Determine the efficiency percentage (η = ps/pt) for μ = 0.5. Herein, Ps and Pt are sideband and total powers respectively, and Pt= Ps + Pc , in which Pc is the carrier power. Hint : Take into account the Parseval's property. c. If the AM waveforms corresponding...
