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 p(t) = 2m₁ (t) cos(3600mt) + m₂(t) cos(4800ft) (a) Sketch the signal spectra of (t) if we know that m₁(t) = 5sinc²(200πt - 50m) m₂ (t) = 4sinc(240mt) (b) A receiver to recover signal m₁(t) is shown below. Design the receiver by indicating the values fb, fl. fe, and Bb. 1 y(t) BPF @ fb Bb Hz LPF @ fi Hz mi(t) cos(2π fet)
