Write python program to plot the zeros and poles if a user provides the coefficients for the numerator and denominator of the transfer function. Since the zeros and poles can be complex, this plot is essentially and argand diagram, where the x axis is the real component and the y axis the imaginary component of a given zero or pole. Create a method called plot-poles zeros(num, den) which takes two lists containing the coefficients. Here is an example and the resulting plot. num [1, 3, 7] # yields zeros at -1.5 +/- 2.17945j den = [1, 4, 5, 3] # yields poles at -2.46557, -0.7672143 +/- 0.7925519j plot_poles_zeros(num, den) Imaginary Page 2 Pole-Zero Plot 3 Zeros × Poles 2 1 -2 1 * Real When you write your code you are only allowed to use the packages numpy and matplotlib. Make sure you label the axes, provide a legend and give a title to your plot (See the example plot). Hint: numpy has a method called roots. When given a list of numbers corresponding to the coefficients of a polynomial, it will find the solutions. Make sure you use cross symbol for poles and filled circles for zeros. You can use what ever colors you like. The numpy methods real and imag will let you extract the real and imaginary part of a zero or pole.

![Write python program to plot the zeros and poles if a user provides the coefficients for
the numerator and denominator of the transfer function. Since the zeros and poles can be
complex, this plot is essentially and argand diagram, where the x axis is the real component
and the y axis the imaginary component of a given zero or pole.
Create a method called plot-poles zeros(num, den) which takes two lists containing the
coefficients. Here is an example and the resulting plot.
num
[1, 3, 7] # yields zeros at -1.5 +/- 2.17945j
den = [1, 4, 5, 3] # yields poles at -2.46557, -0.7672143 +/- 0.7925519j
