{\bf The S-plane }
\end{center}
%\vspace{0.05in}
The purpose of this MATLAB assignment is to gain a better
understanding of the S-plane
and filters. Specifically, you
will be examining the behavior of first and second order high-pass
and low-pass filters of the form $H(s) = \frac{N(s)}{D(s)}$ where
$ N(s)$ and $ D(s)$
are polynomials in terms of $s$. An $n$th order filter of this form
will have $n$ poles and $n$ zeros any of which may or may not be finite.
To test the function of your filter $H(s)$, compute $H(0)$ and $H(\infty)$.
If $H(0)=0$ and $0
