Question: A random process x(n) is characterized by the power density spectrumwhere ?2? is a constant (scale factor).(a) If we view ?xx(f) as the power spectrum

A random process x(n) is characterized by the power density spectrumwhere ?2? is a constant (scale factor).(a) If we view ?xx(f) as the power spectrum at the output of a linear pole-zero system H(z) driven by white noise, determine H(z).(b) Determine the system function of a stable system (noise-whitening filter) that produces a white noise output when excited by x(n). le i2as - 0.91? lei2a-j0.91 leias + j0.912 r..(f) = 0

le i2as - 0.91? lei2a-j0.91 leias + j0.912 r..(f) = 0
