A pole-zero plot shows the location in the complex plane of the poles and zeros of the transfer function of a dynamic system, such as a controller, compensator, sensor, equalizer, filter, or communications channel.

How do you get a pole zero plot?
Zeros and Poles of Transfer Function
Use zplane to plot the poles and zeros of the transfer function. Visualize the zero-phase response of the filter. Overlay the unit circle and the pole and zero locations.
What is pole and zero of a system?
Poles and Zeros of a transfer function are the frequencies for which the value of the denominator and numerator of transfer function becomes zero respectively. The values of the poles and the zeros of a system determine whether the system is stable, and how well the system performs.
Why do we plot poles and zeros?
Pole-Zero plot is an important tool, which helps us to relate the Frequency domain and Z-domain representation of a system. Understanding this relation will help in interpreting results in either domain. It also helps in determining stability of a system, given its transfer function H(z).
What is poles and zeros in Z transform?
Introduction to Poles and Zeros of the Z-Transform
The two polynomials, P(z) and Q(z), allow us to find the poles and zeros of the Z-Transform. The value(s) for z where P(z)=0. The complex frequencies that make the overall gain of the filter transfer function zero.
