(c) Fig. 7 depicts a block diagram of a system which accepts signal, m(t) and produces output, y(t). The spectrum of the input signal, M(w) is shown in Fig. 8 and note that c₁ (t) = cos(wct), c₂(t) = 2cos(wct). m(t) x(t) y(t) i. ii. X C₁(t) c₂(t) WM<<Wc Fig. 7 M(w) -WM 0 WM Fig. 8 Sketch the signal spectrum at the output of the demodulator, Y(w). Modify the system in Fig. 7 so that system able to retrieve the original M(w). Sketch the final output and explain how you achieve it.
