Question: Noise n (t) has the power spectral density shown in Figure 7.16. We write n(t) = n c (t) cos (2Ïf 0 t + θ)

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

n(t) = nc (t) cos (2πf0t + θ) - ns (t) sin(2πf0t + 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 nc (t) and ns (t) uncorrelated?


Figure 7.16S„f) No -f f2 -fi 0 fi -f2

Sf) No -f f2 -fi 0 fi -f2
