The second order approximation using dominant pole concept of a system having transfer function 5/(s+5)(s<sup>2</sup>+s+1) is:
The maximum overshoot is:
Assertion (A): It is desirable that the transient response be sufficiently fast and sufficiently damped.<br>Reason (R): Oscillations are not tolerated in the transient response.
The unit impulse response of a second order system is 1/6e<sup>-0.8t</sup>sin(0.6t). Then the natural frequency and damping ratio of the system are respectively.
