(4) [10 points] Figure 4 is the block diagram of Quadrature amplitude modulation (QAM). Mathematically derive and describe the modulated signals (t); and the signals right before the low-pass filter (L.P.F.), 7₁(t) and x₂(t). Describe how we can restore the original message signals, mi(t) and m₂(t) from ri(t) and 2(t), respectively, via passing through the L.P.F. m (1) m₂(1) TT/2 cos @ sin o PQAM(1) 2 cos @!
