(a) Using MATLAB, plot the gain and phase of the transfer functions below:

\[
\begin{aligned}
& T_{1}(s)=\frac{5000}{s+1000} \\
& T_{2}(s)=\frac{10 s}{s+2000}
\end{aligned}
\]

(b) From the plots, determine which is the high-pass circuit, which is the low-pass, and their respective cutoff frequencies? What is the gain of each?

(c) Explain why the phase changes from \(s=0\) to \(s ightarrow \infty\) in each case?
