Less expensive

Q9. Assertion (A): The phase angle plot in Bode diagram is not affected by variation in the system gain.

Reason(R): the variation in the gain of the system has no effect on the phase margin of the system.

Both A and R are true but R is correct explanation of A

Both A and R are true but R is incorrect explanation of A

A is true but R is false

A is false but R is true

Q10. The disadvantages of the linear system are:

The constraints on the linear operation over wide range demands unnecessarily high quality.

The restriction to the linear theory may inhibit the designer’s curiosity to deliberately introduce the non-linear components.

Practically systems are non-linear
