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.

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.

What does a pole-zero plot show?

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 to plot poles and zeros of transfer function in matlab?

h = pzplot( sys ) plots the poles and transmission zeros of the dynamic system model sys and returns the plot handle h to the plot. x and o indicates poles and zeros respectively. h = pzplot( sys 1, sys 2,..., sys N) displays the poles and transmission zeros of multiple models on a single plot.
