Find an (N) th-order AR approximation for the ARMA system [H(z)=frac{left(1-0.8 z^{-1} ight)left(1-0.9 z^{-1} ight)}{left(1-0.5 z^{-1} ight)left(1+0.5
Question:
Find an \(N\) th-order AR approximation for the ARMA system
\[H(z)=\frac{\left(1-0.8 z^{-1}\right)\left(1-0.9 z^{-1}\right)}{\left(1-0.5 z^{-1}\right)\left(1+0.5 z^{-1}\right)}\]
and compare the resulting magnitude response with the original ARMA system.
