The slope of log magnitude asymptote changes by - 40 dB/ decade at a certain frequency and the error between asymptote and actual curve is - 6 dB. This means that
a double pole is present
a pair of complex conjugate poles is present
either a double pole or a pair of complex conjugate poles is present
either a pole or zero at that frequency is present
