Question# 3:
A random process Y(t) has the power spectral density
S_YY(w) = 16 / (w^2 + 64)
a. Find the average power in the process Y(t).
b. Find the autocorrelation function of Y(t).
Question# 4:
A random process X(t) has a power spectral density given by
S_XX(w) = { 4 - w^2 / 9, |w| <= 6; 0, otherwise
Determine the average power in the process.
