Which of the following features is not associated with Nichols chart?
A.(0 dB, -180°) point on Nichols chart represent critical Point (-1, 0)
B.It is symmetric about -180°
C.M loci are centred about (0 dB, -180°) point
D.The frequency at intersection of G(jω) locus and M = +3 dB locus gives bandwidth of closed loop system
