Frequency Response Magnitude and Poles and Zeros 

What is this magic that I never learned

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

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

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

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

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.

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

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

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! :-)

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

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

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).

Probably the best instructor I have come across on youtube

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

Love u prof.😊

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

So cool!!!!!!!!

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

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

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!

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 ;-;

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

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

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)?

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

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!

great plot and wonderful explanation!!!

Thanks. Glad to see an american doing these videos.

Amazing video! Thank you!

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

brilliant video. Thank you

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

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

Thanks a lot this is a great intuitive video

Amazing explanation thanks.

Is poles only at z:0 occurs?

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

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

Song name please

Thank for your Videos

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

I cannot express how thankful i am for these videos

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

thanks very much

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

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

This helps me a lot, thank you :-)

Very fantastic thank you

I GET IT FINALLY!!!!!

wish my professor were at least one tenth as clear

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?

Great video ! Thanks

very explanatory.. thanks a lot for the effort

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

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

Incredibly excellent content .

this is an amazing video tbh

Fantastic video, great job

Amazing! Thank you very much!

Your videos are one of my all time favorites .

Excellent explanation sir

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

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

very clear description Thank you!

Fantastic video. Thanks Mike F.

Landed a jackpot!

Well explained... thank you

Excellent explanation

Very nice one! Thanks.

Thank you!!!!!

Thanks !

Mindblown.

thank you
