How do you plot poles and zeros of a transfer function?

In the general case of a transfer function with an mth order numerator and an nth order denominator, the transfer function can be represented as: The pole-zero representation consists of the poles (p_i), the zeros (z_i) and the gain term (k). Note: now the step of pulling out the constant term becomes obvious.

How do you find the pole-zero plot?

By convention, the poles of the system are indicated in the plot by an X while the zeros are indicated by a circle or O. A pole-zero plot can represent either a continuous-time (CT) or a discrete-time (DT) system. For a CT system, the plane in which the poles and zeros appear is the s plane of the Laplace transform.

What is a zero pole transfer function?

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.

Is it possible to plot the pole-zero using Z transform?

Once the poles and zeros have been found for a given Z-Transform, they can be plotted onto the Z-Plane.
