Frequency Response Magnitude and Poles and Zeros

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.

[@cemonatk]

Incredibly excellent instructional content.
I've never understood so well this topic before.

[@gokulakrishnancandassamy4995]

The explanations are crystal clear... Especially the part explaining tracing the magnitude response based on the PZ-plot. Thank you, prof. Barry!

[@mxdog45]

What is this magic that I never learned

[@ehtesamulazim5887]

Probably the best instructor I have come across on youtube

[@petertwiss356]

How could you even consider giving this a thumbs down? People are just assholes. This video is gold.

[@SirHiggalot]

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.

[@fahimhafiz2091]

one of the best videos I came across in DSP.Thanks a Lot!

[@dakotahrivers6640]

I cannot express how thankful i am for these videos

[@rebeccaliang8915]

Your videos are one of my all time favorites .

[@fontanads]

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!

[@vovaparkourukraine1]

Incredible. This is the type of shit we need for genuine comprehension

[@CSmyth89]

Excellent video, thank you.
Something tells me I'll be on your channel quite a bit over the xmas holidays.

[@oscarbecerril8343]

Your videos are perfect, beautiful, a excellent resource. Thanks a lot.

[@mariama8157]

Thanks a lot Prof.Barry for your great videos. I hope to see more videos in the future.

[@johannarigby245]

This video was fantastic! I really appreciate your clear explanations :)

[@imbecileheureux119]

Very clear, you helped me for my signal exam. Thank you

[@BlackCapGaming]

Best explanation I've heard (and my prof wrote a book about this stuff lol)

[@jacquelineurena5860]

Thank you for the detail explanation and examples. This helped me so much

[@BangsterDK]

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! :-)

[@user-jg2xf3pj1z]

Excellent. Somethings I never understood in school are explained well.

[@kiowa200488]

It's easy to understand through this video,thank you

[@umarhayat459]

Incredibly excellent content .

[@wkswilliam]

Really good video. You are a excellent teacher. I don`t understand why you have just a few views.
Thank you very much.

[@Mululuc]

great plot and wonderful explanation!!!

[@RajeevD4138]

Sir u r awesome....after so many searches i finely found the explanation. Thanks

[@jseo11]

You are genius............I admired your knowledge... ...You're a reincarnation of Fourier..............Thanks...

[@mikefredd3390]

Fantastic video.
Thanks Mike F.

[@IvanIvan-lc6rm]

Amazing video! Thank you!

[@joshchangt]

very clear description
Thank you!

[@samchow10]

Thank you for the video. What tool are you using to do the pole zero plots and then graph the frequency response?

[@allsignalprocessing]

Thanks for the complement. In case you haven't found my channel, there are about 100 and growing at present.

[@jayasai9128]

Barry Van Veen poles occur only at z=0?

[@UserUnknown123__]

Thanks a lot this is a great intuitive video

[@nyctosissmite2464]

Fantastic video, great job

[@ahmetcihatbozkurt8081]

Amazing explanation thanks.

[@omartubes]

very explanatory.. thanks a lot for the effort

[@BenjaminYoung1]

brilliant video. Thank you

[@anderbush4741]

Thank for your Videos

[@MukeshChaudharyiitg]

Excellent explanation

[@yiweigui1645]

thank you for the video!!! help me a lot!

[@drehkick32]

Amazing! Thank you very much!

[@JanezKrnc-San]

Great video ! Thanks

[@fathimaruzaiqa9489]

Well explained... thank you

[@saharkhawatmi660]

Very nice one! Thanks.

[@buttbhutti6093]

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

[@samarpanguha5512]

Excellent explanation sir

[@bobby2636]

This helps me a lot, thank you :-)

[@ashes2776]

very nice video sir ,i would like more such videos for s-plane phasor for poles and zeroes

[@skylercornell7996]

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!

[@rogercastellanosfernandez3551]

this is an amazing video tbh

[@emmanuelcarvalho9193]

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)?

[@DnTk]

Mindblown.

[@israamohamed7160]

Very fantastic
thank you

[@tars5104]

Love u prof.😊

[@ajingolk7716]

In the equation of 3rd order filter pll something called pole and zero pop up what are they? Thank you

[@hesap1342]

thanks very much

[@lyapunovnchill3028]

Great video
How come your example at 6:39 has a zero ?
I would think it is an all-pole filter ?

[@ahsanbaig8569]

Landed a jackpot!

[@yashodhanjoshi781]

thank you

[@ridwanabrar1003]

Thanks !

[@DewTime]

Thanks. Glad to see an american doing these videos.

[@PankajSingh-dc2qp]

@ 1:11 the product in pole-zero form should start from k=1.

[@mikehagerty9666]

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).

[@samuelgoldburg3793]

I had the same thought. In Oppenheim and Schafer the indices of the products in this expression are from k = 1.

[@chandrahasp6697]

So cool!!!!!!!!

[@dionysiospiskopos2398]

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?

[@emmanueloluga9770]

Yes you van

[@TheAndrem95]

Thank you!!!!!

[@user-xk4vj9nk7k]

Song name please

[@jayasai9128]

Is poles only at z:0 occurs?

[@yogurtpimple3455]

I GET IT FINALLY!!!!!

[@PankajSingh-dc2qp]

@ 3:50 the direction of the vector is wrong... it should be in the opposite direction

[@valtih1978]

I do not get how z-series is related to frequency.

[@ritheshkumar4240]

[@perrosovietico7605]

How the hell did I end up here, I was just watching turtles in heat ;-;

[@kaursingh637]

my lord - analog circuit ==poles and zeros are given-- how to plot frequency response ? thank u my lord =amarjit - india

[@nurullahozdemir697]

Guys do you know that how can I help him, financially?

[@NingNeilXie]

wish my professor were at least one tenth as clear
