Graphical interpretation of the magnitude response of a system described by a linear constant-coefficient difference equation in terms of the locations of poles and zeros in the z-plane.
Great video, as many others in the channel. It was exactly the insight on Z-plane pzmap analysis for digital filter design I was looking for. Thank you very much!
Can we manually sketch a Bode Plot of the frequency response from the Z-Transform. Like we do with the Laplace Transform. -20 dB/Decade for where Poles lie and 20 dB/Decade for Zeroes, type of a thing
Is the frequency response beyond w=pi of any interest to us? Would we expect to see copies of the same frequency response every multiple of 2pi radians? Thanks!
Someone knows how the sample rate affects the transfer z function H(z)? For example: if I want a filter with two poles, central frequency of 500Hz, deltaf of 32Hz and sample frequency of 10kHz, how to determine the transfer function H(z)?
I will like to know, is there any kind of way to determine from a H(z) function, the capacitors-inductances of a filter? I mean can i transfer this model to the real wolrd?
Thanks again for the videos. At [2:30] The expression for poles and zeros has the products running from k=0 to k=M (or N). Probably this should be from k=1 ? e.g., system has M (N) zeros (poles).
Incredibly excellent instructional content.
I've never understood so well this topic before.
How could you even consider giving this a thumbs down? People are just assholes. This video is gold.
Incredible. This is the type of shit we need for genuine comprehension
The explanations are crystal clear... Especially the part explaining tracing the magnitude response based on the PZ-plot. Thank you, prof. Barry!
What is this magic that I never learned
Probably the best instructor I have come across on youtube
This is incredibly helpful. I don't understand why I was not showed this when i took signals and systems 1. Thanks you for sharing.
one of the best videos I came across in DSP.Thanks a Lot!
I cannot express how thankful i am for these videos
Excellent video, thank you.
Something tells me I'll be on your channel quite a bit over the xmas holidays.
Your videos are one of my all time favorites .
Great video, as many others in the channel.

Thank you very much!
Thanks a lot Prof.Barry for your great videos. I hope to see more videos in the future.
This video was fantastic! I really appreciate your clear explanations :)
Very clear, you helped me for my signal exam. Thank you
Your videos are perfect, beautiful, a excellent resource. Thanks a lot.
Best explanation I've heard (and my prof wrote a book about this stuff lol)
I really enjoyed your video! It helped me out alot, as I was trying to find this information in a very confusing textbook - THANK YOU! :-)
Thank you for the detail explanation and examples. This helped me so much
Excellent. Somethings I never understood in school are explained well.
Thank you for the video. What tool are you using to do the pole zero plots and then graph the frequency response?
great plot and wonderful explanation!!!
Really good video. You are a excellent teacher. I don`t understand why you have just a few views.
Thank you very much.
It's easy to understand through this video,thank you
Sir u r awesome....after so many searches i finely found the explanation. Thanks
Fantastic video.
Thanks Mike F.
Incredibly excellent content .
You are genius............I admired your knowledge... ...You're a reincarnation of Fourier..............Thanks...
very clear description
Thank you!
Amazing video! Thank you!
very explanatory.. thanks a lot for the effort
Fantastic video, great job
Thanks a lot this is a great intuitive video

Thanks for the complement. In case you haven't found my channel, there are about 100 and growing at present.
Barry Van Veen poles occur only at z=0?
thank you for the video!!! help me a lot!
Amazing explanation thanks.

Amazing! Thank you very much!

Thank for your Videos
very nice video sir ,i would like more such videos for s-plane phasor for poles and zeroes
brilliant video. Thank you
Excellent explanation
Great video ! Thanks
Well explained... thank you
Very nice one! Thanks.
This helps me a lot, thank you :-)
Excellent explanation sir
Great video
How come your example at 6:39 has a zero ?
I would think it is an all-pole filter ?
In the equation of 3rd order filter pll something called pole and zero pop up what are they? Thank you
this is an amazing video tbh
Very fantastic
thank you
I will like to know, is there any kind of way to determine from a H(z) function, the capacitors-inductances of a filter? I mean can i transfer this model to the real wolrd?
Yes you van
Song name please
@ 1:11 the product in pole-zero form should start from k=1.
Love u prof.😊
thank you
Is poles only at z:0 occurs?
Landed a jackpot!
Mindblown.
thanks very much
Thanks again for the videos. At [2:30] The expression for poles and zeros has the products running from k=0 to k=M (or N). Probably this should be from k=1 ? e.g., system has M (N) zeros (poles).
I had the same thought. In Oppenheim and Schafer the indices of the products in this expression are from k = 1.
Thanks !
So cool!!!!!!!!
Thank you!!!!!
@ 3:50 the direction of the vector is wrong... it should be in the opposite direction
Thanks. Glad to see an american doing these videos.
I do not get how z-series is related to frequency.
I GET IT FINALLY!!!!!
Guys do you know that how can I help him, financially?
my lord - analog circuit ==poles and zeros are given-- how to plot frequency response ? thank u my lord =amarjit - india
How the hell did I end up here, I was just watching turtles in heat ;-;
wish my professor were at least one tenth as clear
