3. Two messages m(t) and m(t) were transmitted on carriers cos(24 t) and cos(21 ft+r/2), respectively to obtain the transmitted signal s(t)= m(t) cos(20 ft)+ m2(t) cos(21 ft+r/2) The receiver is as shown in Figure 3. Find the output î, (t). Is it possible to separate the messages m, (t) and m2(t) using this receiver (i.e. the output î, (t) should not contain the term proportional to m(t))? 5 marks LPF ñ(t) Х cos(21fct) s(t) TT/2 TT/2 phase shift LPF х Fig. 3 LPF = Low pass filter.
