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.
The constant Mcircle represented by the equation x^{2} + 2.25x + y^{2} = 1.25 has the value of M equal to:
The constant N loci represented by the equation x^{2} + x + y^{2} = 0 is for the value of phase angle equal to:
Consider the following statements:
Nichol’s chart gives information about.
i. Closed loop frequency response.
ii. The value of the peak magnitude of the closed loop frequency response Mp.
iii. The frequency at which Mp occurs.

In a bode magnitude plot, which one of the following slopes would be exhibited at high frequencies by a 4th order allpole system?
Nichol’s chart is useful for the detailed study and analysis of:
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.
