Question:

Obtain the auto correlation functions and power spectral densities of the outputs of the following systems with the input auto correlation functions or power spectral densities given.

(a) Transfer function:

H(f) = II(f / 2B)

Auto correlation function of input:

No 6(7) Rx(t) = 2 %3D

N₀ and B are positive constants.

(b) Impulse response:

h(t) = A exp(-Î±t) u(t)

Power spectral density of input:

S_X (f) = B / 1 + (2Ï€Î²f)²

A,Î±, B, and Î² are positive constants.
