Assertion (A): The phase angle plot in Bode diagram is not affected by the variation in the gain of
the system.
Reason(R): The variation in the gain of the system has no effect on the phase margin of the system.

phase of the system response at 20 Hz is :

10.

Assertion (A): Relative stability of the system reduces due to the presence of transportation lag.
Reason (R): Transportation lag can be conveniently handled by Bode plot.
