Q7)
Correct Statement is: (d) None of the above is correct.
Explanation: The time required for a system to settle within a certain percentage of the input is called SETTLING TIME.
Q8)
Correct Statement is: (a) The state-variables of a system comprise a set of variables that cannot describe the future response of the system, when given the present stane, ali uture Excitation inputs, and the mathematical model
describing the dynamics.
Explanation: From the definition of the state variable system this conclusion is derived.
Q9)
Correct Statement is: (b) For a second-order system with no zeros, the percent overshoot to a unit step is a function of only the damping ratio.
