Very urgent!! Advanced digital signal processing question
Given an uncorrelated zero-mean unit-variance signal u[n] and a signal x[n] = h[n] * u[n], where is the convolution operator, and h[n] = 8[n] +8[n – 1] the impulse response of a system, (1) state the auto-correlation sequence ruu [t] of u[n]; (ii) determine the auto-correlation sequence of x[n]; (iii) calculate the power spectral density Rxx (ell) of x[n], and sketch Rxx(ell) for 0 < 1< 27t; and (iv) determine the power of x[n].
