## Step-by-step Nyquist plot example. Part II

Second part of our posts on the Nyquist plot. This time with a non-minimum-phase transfer-function.

We continue our saga of hand sketches of the straight-line approximations for the magnitude and phase of Bode plot diagrams (Section 7.1). This time we consider a non-minimum phase system with a pole at the origin. See Part I, Part II and Part III, for simpler examples.

We have gone step-by-step over how to sketch straight-line approximations for the magnitude and phase diagrams of the Bode plot for a simple rational transfer-function. This transfer-function had only left-hand side poles and zeros, that is it was *minimum-phase* (see Section 7.2). In this post we consider a *non-minimum phase* transfer-function with a right-hand side zero. See Section 7.1 for details on the approximations.
