Consider the two signals c₁ (t) = 4 cos(50000πt) and c₂ (t) = 4 sin(50000πt). The real and the imaginary parts of the spectrum of two signals, m₁(t) and m₂(t), are shown in the following figure. M₂(f) M₁D Re Im -5000 M₁(f) -5000 10 0 5000 f-> 5000 f-> -5000 M₂(f) -5000 5000 f-> 5000 1) Draw the real and the imaginary parts of the spectrum of z(t) = m₁(t)c₁(t) + m₂(t)c₂(t). 2) Draw the real and the imaginary parts of the spectrum of w(t) = m₁(t)c₁(t) — m₂(t)c₂(t). 3) If z(t) is multiplied by c₂(t), then integrated (or equivalently, passed through a LPF), what will be the output signal? 4) If w(t) is multiplied by c₂(t), then integrated (or equivalently, passed through a LPF), what will be the output signal?
