ANSWER. (a) The process {X_f} is a linear combination of the purely random process {ϵ_f}. If {ϵ_f} has mean zero and variance σ^2, then it follows that {X_f} also has mean zero. To find the variance of {X_f}, we can use the formula for the variance of a linear combination of random variables: View the full answer.
