A stationary random process n(t) has a power spectral density of 10^{-6 }W/Hz, -∞ < f < ∞. It is passed through an ideal low pass filter with frequency response function H(f) = II (f / 500 kHz), where II(x) is the unit-area pulse function defined in Chapter 2.

(a) Find and sketch the power spectral density of the output?

(b) Obtain and sketch the auto correlation function of the output.

(c) What is the power of the output process? Find it two different ways.
