A Nyquist plot is a parametric plot of a frequency response used in automatic control and signal processing. The most common use of Nyquist plots is for assessing the stability of a system with feedback. In Cartesian coordinates, the real part of the transfer function is plotted on the X -axis while the imaginary part is plotted on the Y -axis.

Posted on ...Transfer function stability is solely determined by its denominator. The roots of a denominator are called poles. Poles located in the left half-plane are stable while poles located in the right half-plane are not stable. The reasoning is very simple: the Laplace operator "s", which is location in the Laplace domain, can be also written as:
