Figure 3 is the block diagram of Quadrature amplitude modulation (QAM). Mathematically derive and describe the modulated signals 4QAM(t); and the signals right before the low-pass filter (L.P.F.), x1(t) and x2(t). Describe how we can restore the original message signals, m₁(t) and m₂(t) from x₁(t) and x2(t), respectively, via passing through the L.P.F. m₁(1) Low-pass x₁(1) filter m₁(t) cos w 2 cos w Σ -π12 4QAM(1) -π12 sin w 2 sin w m₂(1) x2(1) Low-pass filter m2(t) Fig. 3: Quadrature Amplitude Modulation
