Problem 1.1
an 8th order discrete time system is described by the following difference equation:
where
a = {1.0000

(a) using the MATLAB function impz(), give the commands needed to find the impulse response
h(n) of the system. Also how would you use the stem() function to make a stem plot of h(n)?
(b) Using the MATLAB function filter(), give the commands needed to find the same impulse
response as in (a).
(c) Using the MATLAB function conv(), give the commands needed to calculate the linear convo
lution of h(n) and u(n).
(d) Using the MATLAB function freqz(), give the commands needed to calculate the frequency
response of the filter.
