Question

In op-amp circuits or other circuits containing active amplifier devices, we sometimes obtain a term of the form H(s)=(1-s/w0) where w0 is a positive real constant. This is called a “right half-plane zero” or “nonminimum phase zero” because it has a root with a positive real part.

3. In op-amp circuits or other circuits containing active amplifier devices, we sometimes obtain a term of the form His) = (1- His) = | | "nonminimum where is a positive real constant. This is called a "right half-plane zero" or phase zero" because it has a root with a positive real part. (a) Compared with the standard (left half-plane) zero discussed in class, what is the effect of the minus sign on the magnitude and phase of H(s)? (b) Sketch the magnitude asymptotes of H(s), and label the salient features (i.e., label the slopes of the asymptotes, the break frequency where the asymptotes intersect, and the magnitude of the asymptotes at the break frequency) e) Sketch the phase asotesa r salien features

Explanation / Answer

Non minimum phase zero system
