# Question: The input X k to a filter is a

The input, X [k] , to a filter is a discrete- time zero- mean random process whose autocorrelation function is RYY [n] = δ [n]. The input/ output relationship of the filter is given by

A certain LTI system has an input/ output relationship given by (a) Find the output autocorrelation, RYY (τ), in terms of the input autocorrelation, RXX (τ). (b) Find the output PSD, SYY (τ), in terms of the input PSD, ...A filter has an impulse response of h (t) = te– t u (t). Find the noise equivalent bandwidth of the filter. A one- sided exponential pulse, s (t) = exp (– t) u (t), plus white noise is input to the finite time integrator. Adjust the width of the integrator, to, so that the output SNR is maximized at t = to. Suppose we are allowed to observe a random process Z (t) at two points in time, t0 and t2. Based on those observations we would like to estimate Z (t) at time t = t1 where t0 < t1 < t2. We can view this as an interpolation ...Calculate the spectrum for in Exercise 11.5 if AndPost your question
