where all our poles are in the left-half plane‚ the contribution the response for a given value of “a” dies out faster if the pole is farther to the left ( since exp(-a*t) approaches zero faster for larger “a”. Therefore‚ the pole closest to the imaginary axis are the ones that tend to dominate the response since their contribution takes a longer time to die out. Our additional pole 1/(1+alpha ) is a first order system while our original transfer function G(s) is a second order system In this
