A linear time-invariant system is implemented in MATLAB by the following statement y=filter([1 -2 1], [1 -1.81 .81], x) where x is a vector of input samples. Write a MATLAB statement for generating necessary input vector x needed to compute samples of the impulse response h[n] of this system for 0 lessthanorequalto n lessthanorequalto 100. What is the system function H(z) of the system?

Solution

MATLAB statement:

x=linspace(0,5,100);

y=filter([1 -2 1],[1 -1.81 0.81],x);

stem(x)

hold on

stem(y,\'-r\')

hold off
