Automatic Control Systems Which of the following features is not associated with Nichols chart? It is symmetric about -180° M loci are centred about (0 dB, -180°) point The frequency at intersection of G(j?) locus and M = +3 dB locus gives bandwidth of closed loop system (0 dB, -180°) point on Nichols chart represent critical Point (-1, 0) It is symmetric about -180° M loci are centred about (0 dB, -180°) point The frequency at intersection of G(j?) locus and M = +3 dB locus gives bandwidth of closed loop system (0 dB, -180°) point on Nichols chart represent critical Point (-1, 0) ANSWER DOWNLOAD EXAMIANS APP
Automatic Control Systems If any term in the first column of a Routh array becomes zero, then Routh criterion cannot be used to determine stability Routh criterion can be used by substituting a small negative number for zero and complet-ing the array Routh criterion can be used by substituting a small positive number for zero and completing the array Routh criterion can be used by substituting a big positive number for zero and completing the array Routh criterion cannot be used to determine stability Routh criterion can be used by substituting a small negative number for zero and complet-ing the array Routh criterion can be used by substituting a small positive number for zero and completing the array Routh criterion can be used by substituting a big positive number for zero and completing the array ANSWER DOWNLOAD EXAMIANS APP
