Some simple sufficients conditions and necessary conditions are presented for analyses when zeros located between the dominant and fastest pole does not cause extrema in the step-response. These conditions require knowledge of the pole-zero configuration of the corresponding transfer-function.1025-1031porTransfer functionsStep-responsePoleZero extremaArtigo10.1109/TLA.2011.6129698WOS:000300191300008Acesso restrito
