Automatic Control Systems Which of the following features is not associated with Nichols chart? It is symmetric about -180° The frequency at intersection of G(j?) locus and M = +3 dB locus gives bandwidth of closed loop system M loci are centred about (0 dB, -180°) point (0 dB, -180°) point on Nichols chart represent critical Point (-1, 0) It is symmetric about -180° The frequency at intersection of G(j?) locus and M = +3 dB locus gives bandwidth of closed loop system M loci are centred about (0 dB, -180°) point (0 dB, -180°) point on Nichols chart represent critical Point (-1, 0) ANSWER DOWNLOAD EXAMIANS APP
