Signal Processing

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).

(10 pts) The steady-state.response of a stable system.to a sinusoidal input function will, itself, bea sinusoid of the same frequency as the input function, with the only difference being the ratio of input to output amplitude, and a phase shift between the input and output sinusoids. Using the transfer function for the system (T(s) relating the input, u, to the output, y), how can you mathematically determine the amplitude ratio and the phase shift for a given input sinusoidal frequency, w?
