For critically damped system, the value of the damping ratio $\zeta$ is:

A unit step input is applied to the negative feedback system whose closed loop transfer function is $\frac{63}{S^2 + 4.8S + 9}$, then the steady state value of the output is}

The derivative of a parabolic function becomes

The capacitance, in force-current analogy, is analogous to

For overdamped systems, the closed loop poles are
