Butterworth Filter - 03 - Frequency Scaling

[@grantbell8143]

I have been searching the web for days trying to learn this stuff. You have put all the pieces of the puzzle together for me. Thank you

I've been struggling in this class all semester, and none of the videos I'd watched had helped at all, until I found your channel. Thanks a ton!!

Thank you Adam Panagos, you have a great ability of simplifying and explaining things; If you cant explain something to a six year old, you don't understand it yourself. Einstein would be proud! :)

[@AdamPanagos]

Awesome, thanks so much for the nice comment!

[@agstechnicalsupport]

Great video explaining frequency scaling, relationship between filter order, pass band and stop band frequencies and gain, and calculation of cutoff frequency in Butterworth filters.

I was reading Sedra/Smith and they included a fudge factor epsilon that made this more painful than it had to be, but after watching your video series it really cleared things up. Your presentation is top notch, Thank You!

[@AdamPanagos]

Thanks!

Excellent teaching. Thanks a lot.

Thank you very much Mr. Panagos, your videos helped me alot

I'm sorry, but when you say that you're going to use algebra to solve the equation (4:40 min) I couldn't follow your calculus. Is there any video which I could watch to understand it better? Thank you and congrats for this fantastic job!

[@AdamPanagos]

At the 4:40 mark you're talking about how I simplified the 20log10() quantity? That's really not calculus, it's just properties of logarithms. We have 20log10(x/y) = 20log10(x) - 20log10(y). Since log10(1) = 0, that results in 0 - 20log10(y). Similarly, if we have 20log10(x^(1/n)), by properties of the logarithm this is (1/n)20log10(x). Hope that helps. Adam

Thank you, Adam. I admire your remarkable method and your explanation , much appreciated. please if possible explain the same for chebychev.....for sure, you've got the potential ability to a distinguished teacher for the 1 st class..kind regards

[@AdamPanagos]

Thanks for the kind words; I'd love to get a Chebychev video series made as well, just haven't had the time yet. Best!

[@SassynSaxy]

What's the difference between the passband frequency and the cutoff frequency? I'm having trouble finding an answer that differentiates the 2

[@wasaybaig1705]

Please tell how to do this for a bandpass filter. I have the equation but I can't scale it 😭

[@samtriebels8742]

love your work

[@abhishekjana3674]

sir very very much thank you. I was stuck in this topic and try to understand from book. but after reading 3/4 I just can't understand a single word. but I watched this videos one time, its become too easy.

[@AdamPanagos]

Glad to hear that, thanks!

[@kherboucha1]

Thank You So Much , that really helped me to get a lot of stuffs .. May God Be With You And Reward You :D

[@AdamPanagos]

Awesome, glad you found it useful.

[@sam78ize]

amazing tutorial. thanks

[@Nxb9ch]

can you upload Chebyshev response (Type-I) for lowpass within the next 6 hours? I need to face a class test.

[@PunmasterSTP]

Out of curiosity, how'd your test go?

[@Nxb9ch]

@@PunmasterSTP Professor didn’t publish the course result, but one of my close friends elaborated the whole concept.

[@PunmasterSTP]

@@Nxb9ch I'm glad for that!

[@kcha986]

and the phase lag formula?

[@ArjunaWeerasinghe]

really helpful

[@AdamPanagos]

Thanks!

[@vishnubhaskaran2521]

thanks to you sir :)

I tryed to understand with Daryanani's book, but I just undedrstood with you
