Question:

Consider again the system of Fig. P4.4-5. Add a sampler for \(E(s)\) at the input. Given

\[
G_{1}(s)=\frac{1}{s+10} \quad D(z)=\frac{z-0.5}{z-1} \quad G_{2}(s)=\frac{s}{s^{2}+9 s+23}
\]

find \(c(k T)\) for a unit-step input with \(T=0.5 \mathrm{~s}\). Is this a good choice for the sampling interval? If not, what sampling rate would you recommend. Find \(c(k T)\) at your recommended sampling rate and plot both step responses using MATLAB.
