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 plot impulse response?

To create impulse plots with default options or to extract impulse response data, use impulse . h = impulseplot( sys ) plots the impulse response of the dynamic system model sys and returns the plot handle h to the plot. You can use this handle h to customize the plot with the getoptions and setoptions commands.

How do you find the impulse response from a transfer function?

To find the unit impulse response of a system we simply take the inverse Laplace Transform of the transfer function.

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).
