Noise n (t) has the power spectral density shown in Figure 7.16. We write

n(t) = n_c (t) cos (2Ï€f₀t + θ) - n_s (t) sin(2Ï€f₀t + θ)

Make plots of the power spectral densities of nc(t) and ns (t) for the following cases:

(a) f₀ = f₁

(b) f₀ = f₂ 

(c) f₀ = 1/2(f₂ + f₁) 

(d) For which of these cases are n_c (t) and n_s (t) uncorrelated?
