In summary, a Nyquist plot is a graphical representation of a system's frequency response in the complex plane. It can be constructed from a polar plot by reflecting the plot and connecting the two halves. The plot can provide information about system stability and performance, and has the advantage of being visually intuitive and allowing for easy comparison of different systems. However, it may not be applicable to all types of systems and its accuracy depends on the accuracy of the frequency response data.

Is it possible to construct Nyquist plot from polar plot (ω varies from ∞ to 0) ?
Yes, for a system with no poles or zeros on the Nyquist path, the Nyquist diagram is simply the polar plot of the open-loop function along with its complex conjugate.
