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