Modulation And Demodulation
Modulation is the process of converting data into radio waves by adding information to an electronic or optical carrier signal There are three types of modulation namely: 1. Frequency modulation 2. Amplitude modulation 3. Phase modulation Demodulation is defined as extracting the original information carrying signal from a modulated carrier ...

SOLVED:Amplitude modulation with a pulse-train earlier may be modeled as in Figure P8.30(a). The output of the system is q(t) (a) Let x(t) be a band-limited signal [i.e., X(j ω)=0,|ω| ≥π/ T], as shown 1 πFigure P 8.30(b) . Determine and sketch R(j ω) and Q(j ω) (b) Find the maximum value of Δsuch that w(t)=x(t) with an appropriate filter M(j ω) (c) Determine and sketch the compensating filter M(j ω) such that w(t)=x(t)

Amplitude-Modulated Wave in a Dispersive Medium. An amplitude-modulated wave whose complex wavefunction takes the form A(t)=[1 m cos(2 πfa t)] (j 2 πv0 t) at z=0, where fs ≪u0, travels a distance z through a dispersive medium of propagation constant β(v) and negligible attenuation. If β(ν0)=β0, β(ν0-f0)=β1, and β(ν0 fn)= β2, derive an expression for the complex envelope of the transmitted wave as a function of β0 ·β1, β2, and z. Show that at certain distances z the wave is amplitude modulated wi
