Web141K views 9 years ago Dynamic Systems and Control. Calculating the magnitude and phase of a transfer function at a point in the complex plane is helpful to understand root locus plots. Web11 jan. 2024 · At t=inf, you have -1/2 (could be found considering s->0 in the transfer function). So the non minimum phase zero in this system, considering a unit step in t=0, makes the output go from zero to positive (t=0, y=1) before coming back to negative (t=+inf, y=-1/2) in steady state. I believe your graph represents just that. WebPhase Transfer Function. For the special case of a symmetric impulse response centered on the ideal image point, the phase transfer function (PTF) is particularly simple, having a value of either zero or π as a function of spatial frequency (see Fig. 1.12). The OTF can be plotted as a bipolar curve having both positive and negative values. intent and intention difference
