Automatic Control Systems If any term in the first column of a Routh array becomes zero, then Routh criterion can be used by substituting a big positive number for zero and completing 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 small negative number for zero and complet-ing the array Routh criterion cannot be used to determine stability Routh criterion can be used by substituting a big positive number for zero and completing 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 small negative number for zero and complet-ing the array Routh criterion cannot be used to determine stability ANSWER DOWNLOAD EXAMIANS APP
