1. Suppose we have the signal x(n) = (0.9)^n u(n-50) as input to the LTI system with impulse response h(n)= (0.8)^n u(n). a) Compute (using a for-loop) and plot the

output y(n) for 0 <= n <= 100. You might want to use the MATLAB function "stem" to plot. b) Compare this to theory. c) Repeat (a-b) for h(n) = (-0.8)^n u(n).
