The estimated auto correlation sequence of a random process x(n) for lags k-0, 1,2, 3,4 are rx(0)-2, rx(1)-1, rx(2)-1, rx(3)-0.5, rx(4)-0 estimate the power spectrum of x(n) for each of the following cases. (b) x(n) is an ma(2) process. (c) x(n) is an arma(1,1) explain the rule of each method step by step
