- An introduction to pole/zero plots.
This video is one in a series of videos being created to support EGR 433:Transforms & Systems Modeling at Arizona State University. Links to the other videos can be found at sites.google.co...
Thank you so much for this! This is very useful in my Analog IC design class where each pole will result in a capacitor! Now I know how to find the poles!
Ẃell explained. Thank you for uploading this.
Thank you Thank you Thank you very well explained exactly what I needed!
thanks for the video! your mistake made me check the roots myself it was a good one! I wish you made this while I was in grad school. thank you thank you thank you *-----*
i am only advocate in india-- but i have under stood lecture completely
Those are the roots of (s^2+4s+13). When s= either of those values you wrote, (s^2+4s+13) will equal zero.
can you please be so kind to explain how you reached the roots -2+j3 & -2-j3
By using the quadratic formula on the quadratic polynomial where j is sqrt -1
very well done thank you..
Very good lecture sir
Could you kindly share the matlab code to plot this 3 axis diagram?
great series of videos these are, esp to control student. i find them easier to understand than the textbooks. i do have one question: is it possible you Sir to write down the MATLAB code for producing those beautiful 3D representation of a pole-zero plot. i would appreciate it if you do. thanks
how did u draw this thing with matlab??
i have the same question
Nice video. I don't understand one part however. In the end the on the left of your basis set the exponential is decreasing which I feel is not consistent with my understanding of the basis set as any thing on the left of the basis set should follow an exponential growth rather than a decay. Because s= sigma + j Omega
and e^(-sigma *t) is positive exponential growth on the left of basis set. Could you clarify this problem ? thanks
what is the graph used for? what do you do with it?, what is need it for?
thank you! can you show how to plot de 3D graphic on matlab
Sir its really good lecture
I do have one doubt that "what are real time applications of poles and zeros"
please reply me sir .......Thank you.
If u ever got your answer pls let me know
and what is the name of the third axis?
PLEASE SHARE YOUR MATLAB CODE FOR THAT PLOT, I AND SO MANY OTHER PEOPLE HAVE BEEN WANTING TO MAKE IT, BUT WE REAAAAAALLLLLLY SEEM TO BE GETTING WRONG PLOTS.
could you show as the matlab code to draw this ? ... thanks
%Running on Matlab 2017
[x,y] = meshgrid(-4: .05: 4);
s = x + (j*y);
z = abs(( s + 1) ./ (s.*(s.^2 + (4.*s) + 13)));
figure;
surf(x,y,z);
xlabel('real');
ylabel('imag');

Why is infinity not a zero?
Elias Bardis Because, rigorously speaking, infinity isn't a value.
I'm still in the grad school. but I couldn't understand this yet.
