Question

Using MATLAB/Octave, and given the filter transfer function $H(z) = \frac{1 + 2z^{-1} + z^{-2}}{1 - 0.5z^{-1} + 0.25z^{-2}}$, use the \"freqz\" command to obtain and to plot: a. Its magnitude frequency response b. Its phase response

          Using MATLAB/Octave, and given the filter transfer function
$H(z) = \frac{1 + 2z^{-1} + z^{-2}}{1 - 0.5z^{-1} + 0.25z^{-2}}$,
use the \"freqz\" command to obtain and to plot:
a. Its magnitude frequency response
b. Its phase response

Using MATLAB/Octave, and given the filter transfer function
H(z) = (1 + 2z^-1 + z^-2)/(1 - 0.5z^-1 + 0.25z^-2),
use the f̈reqzc̈ommand to obtain and to plot:
a. Its magnitude frequency response
b. Its phase response
