2 3 Points Two Signals M T And M T Are To Be Transmitted Simultaneously Over A Channel By A Multiplexing Schem 1 (107.32 KiB) Viewed 50 times

2. (3 points) Two signals m₁ (t) and m₂ (t), are to be transmitted simultaneously over a channel by a multiplexing scheme such that the transmitted signal is y(t) = = 2m₁(t) cos(3600πt) + m₂(t) cos(4800πt) (a) Sketch the signal spectra of y(t) if we know that m₁(t) = 5sinc²(200πt - 50m) m₂(t) = 4sinc(240πt) (b) A receiver to recover signal m₁ (t) is shown below. Design the receiver by indicating the values fò, fɩ, fc, and Bò.
