Question 2 Consider the two signals c₁ (t) = 4 cos(50000πt) and c₂(t) signals, m₁(t) and m₂ (t) with the following spectrum. M₁D -5000 10 5000 f-> = 4 sin (50000πt). Consider also the two M₂(f) -5000 0 5000 1) Draw the real and the imaginary parts of the spectrum of z(t) = m₁(t)c₁(t) + m₂(t)c₂(t). 2) If z(t) is multiplied by c₂ (t), then integrated (or equivalently, passed through a LPF), what will be the output signal? 3) Repeat the previous part if z(t) is multiplied by c₁(t) instead.
