GATE ECE 1999 | Question 2.14
If the closed-loop transfer function $T(s)$ of a unity negative feedback system is given by \[ \mathrm{T}(\mathrm{s})=\frac{a_{n -1} \mathrm{~s}+a_{n}}{\mathrm{~s}^{n}+n_{1} s^{n-1}+\ldots+a_{n-1} s+a_{n}} \] then the steady state error for a unit ramp input is $\frac{a_{n}}{a_{n-1}}$ $\frac{a_{n}}{a_{n-2}}$ $\frac{a_{n-2}}{a_{n-2}}$ zero
If the closed-loop transfer function $T(s)$ of a unity negative feedback system is given by\[\mathrm{T}(\mathrm{s})=\frac{a_{n -1} \mathrm{~s}+a_{n}}{\mathrm{~s}^{n}+n_{1...

GATE ECE 1999 | Question 2.15
Consider the points $s_{1}=-3+j 4$ and $s_{2}=-3-j 2$ in the $s$-plane. Then, for a system with the open-loop Transfer function \[G(s) H(s)=\frac{K}{(s+1)^{4}}\] $s_{1}$ is on the root locus,but not $s_{2}$ $s_{2}$ is on the root locus, but not $s_{1}$ both $s_{1}$ and $s_{2}$ are on the root locus neither $s_{1}$ nor $s_{2}$ is on the root locus.
