(a) The difference equation

y[n] - 0.75y[n - 1] + 0.125y[n - 2 = x[n].

models an LTI system. Find the system transfer function.

(b) Find the unit step response for the system of part (a).

(c) Use MATLAB to check the partial-fraction expansion in part (b).

(d) From part (b), give the values of y[0], y[1], and y[2].

(e) Verify the results of part (d) by solving the difference equation iteratively.

(f) Verify the results in part (e) using MATLAB.
