Figure P7-74 shows the step responses \(v_{\mathrm{C}}(t)\) of two competing series \(R L C\) circuits from two different vendors. The circuits are designed to switch from o to \(10 \mathrm{~V}\) and to meet a specification for a desired circuit with the following characteristic equation:
\[
s^{2}+10 s+100=0
\]
Not all of the details of the actual circuits have been provided because of proprietary reasons, but each vendor has given some information about their respective circuit. Both claim they meet the required specifications.
