WebRelation of amplitude to phase. As we learned from equation , a minimum-phase function is determined completely from its spectrum. Thus its phase is determinable from its … WebAs can be found, the amplitude overshoot with the conventional method is about 12%, and the settling time is about 30 ms. With the proposed method, the overshoot is less than 0.5%, and the settling time is reduced to only 13 ms. Besides, the frequency and phase disturbances caused by the amplitude jump are also smaller with the proposed method.
