Solution:

A system having input x and output y is represented by the differential equation:

(dy/dt) + 3y = (dx/dt) + 2x. Find the transfer function of the system.

(s+3)/(s+2)

(s+2)/(s+3)

(s+2)/3

Solution:

The polar plot of the system is given as shown,
If we add poles to the system and draw a new plot, which option corresponds to the maximum number of poles added?

All have the same number of poles

Solution:

How is the transient response of a system affected?

By changes in the input poles

By changes in the system poles

By changes in the system zeroes and poles

It does not change unless the system is changed

Solution:

The input signals to control systems are not known fully ahead of time, the characteristics of control system which suddenly strain a control system are:

Constant velocity and acceleration

Sudden shock

Sudden change

All of the mentioned

Solution:

The response of an LCR circuit to a step input is over-damped if and only if the transfer function has-

Poles on the negative real axis

Poles on the imaginary axis

Multiple poles on the positive real axis

Poles on the positive real axis

Multiple poles on the negative real axis

Solution:
