1. The sequences y(n) and u(n) are related by the difference equation y(n) = u(n + a) - u(n - a), where a is a constant. Evaluate the autocorrelation function of y(n) in terms of that of u(n).

Step 1
First, we can express y(n) in terms of u(n) as follows: y(n) = u(n + a) - u(n - a) = u(n)u(n + a) - u(n - a)u(n) Show more…

Let x(n) be a stationary random process with zero mean and autocorrelation rx(k). We form the process y(n) as follows: y(n) = x(n) + f(n) where f(n) is a known deterministic sequence. Find the mean my(n) and the autocorrelation ry(k, l) of the process y(n).
