Chebyshev Filter : Design of Low Pass and High Pass Filters

[@sergiokpo434]

Thanks for the video. I was searching information as a crazy student and i had a lot of problems to read the Shauman's Book because i dont like English. Now, you are my god and i will believe in any god that you believe

[@shrikartamirisa1955]

This video was a life saver!

[@poojashah6183]

Barely found topic you explained 👌👌👍

[@jiteshsharma4692]

sir you are doing good work...... keep it up... we all want such kind of knowledge... god bless you...

[@upendrakhang1041]

8:10, how the transfer function is calculated from poles P1, P2 & P3?

[@swalker157]

Can you do an inverse Chebyshev example?

[@matthieutremblay5856]

I have a question concerning the poles. if phik = (2k-1)pi/2N then when k = 2 we should have phi2 = (2*2-1)pi/2*6 = pi/2. Then with the pole the imaginary part should be equal to zero right ? I have like -0,6267 and no imaginary numbers. Could you help me ?

[@bigfist855]

Thanks for your very easy explanation

[@AnggadaAryaPalastra]

Sir, I don't quite get how to find the value of Ho, can you help?

[@chethanvenkatesh7901]

1=H0/(0+0+1.1425)(0+0.6264)

[@paulhker]

Thanks for the video. I have watched this video over 10 times already. I put your equations in excel and I believe I understand how it works. I put it into "TINA" (simulation software from Texas instrument), the gain is 5db with a ripple noise less than 0.55db. The cut-off frequency is about 2500 rad/sec. And the stopband frequency is about 12500 rad/sec after 30db attenuation. Thanks a lot! Do you have an example of a higher-order filter? Let say 5th order.

[@abhishek4665]

how to design this chevyshev filter Synthesize a chebyshev low-pass filter to meet the following specification: 1) load resistance = 600 ohm, 2) 0.5 dB ripple with pass band, 3) cut-off frequency=5x105rad/sec, 4) At 1.5x106 rad/sec, the magnitude must be down 30 dB.

[@jeffsam5495]

at 5:47 the question it says the stopband frequency of the filter is 12500rad/sec with stop band attenuation of 30db or more. why didnt we consider those facts in the calculation.???

[@ALLABOUTELECTRONICS]

It has been used in the equation for finding the order of the filter. Please look at it carefully once again .

[@jeffsam5495]

oh thank you!

[@aylamao9847]

@ALL ABOUT ELECTRONICS When attempting to calculate the order required for a high pass filter should I take the passband and attenuation as the upper frequency as I would for a lowpass filter and the use the s^-1 substitution you demonstrated? Using the equation for calculating the required order with the lower frequency as the pass band seems impossible as arc-cosh must be a value greater than one or am I mistaken. Thanks a lot for your very informative video none the less.

[@mayurshah9131]

Excellent job, God and GURUDEV Bless you

[@adrirajbarua1820]

What is the general transfer function of 4th order chebyshev high pass filter??

[@evolutionarytheory]

The square of the 2nd order one.

[@CaliberJaybodon]

How did you get 1.1424 at 8:15?

[@ALLABOUTELECTRONICS]

In the denominator, there are three terms. (S - P1) (S- P2)(S- P3). Just multiply the first two terms and the put the value of P1, P2 and P3, you will get it.

[@JEDhanraj]

P1=-a+jb P2=-a-jb So the equation will be S^2+(P1+P2)S+P1*P2 here P1+P2 =-2a And P1*P2 =a^2+b^2.

[@eceonder7770]

I need Bessel Filter Design

[@danno9907]

Thank you very much!!!

[@TheJodani]

excellent contribution on active filters. Can you provide some document, paper or book?

[@ALLABOUTELECTRONICS]

Application note of Texas instrument is good. And one chapter (Active filters) of the book "Electronics principles by Albert Malvino " is also good in general for analog filters.

[@namikaze9108]

8:44 how?ho=0.715??

[@ALLABOUTELECTRONICS]

Just you put S=0 in the given expression. You will get H0 = 0. 715

[@muhamadthoriq3523]

it would be better if u add the cc in the video, thanks

[@sehajbrar9815]

Excellent

[@xXxkeepsmiling]

Nice video. But im missing the High Pass Filter Design. How can i obtain the required values for a high pass filter 3rd Order Chebyshev with Sallen-Key Topology? And how can i get the Passband frequency if i only given the -3dB Cut-Off Frequency? Thanks

[@believethat6739]

Sir make video on 2nd order chebyshev low pass filter with electronic circuit and mathematical expression

[@noweare1]

Butterworth filter design seems a little bit easier.

[@pablo-yx4st]

and bessel?

[@jeffsam5495]

how q = root(R1*R2*C2*C2)/(R1*C2+R2*C2) at 15:46

[@sayantanmaiti2513]

look at his previous videos about butterworth....there he found out the expression for Q..... and here he takes a unity gain Sallen Key which has a k=1, so putting k=1 at that Q expression he arrives at this expression

[@TheJodani]

Dear friend, I hope you can help me with a problem. I'm designing a second-order Chebyshev filter: Ap = 3dB (ripple), N = 2, ε = 0.997628 , Gain = 1dB and TF is: H(s) = Ho / (s^2 + 0.6449s + 0.7079) as N=2 then H(s=0) = 1 / √ (1+ε^2) then Ho = 0.5012. The TF of Low Pass Filter is LPF(s) = w^2 / (s^2 + w*s/Q + w^2), if I compare H(s) and LPF(s), then Ho ≠ w^2 because Ho = 0.5012 and w^2 = 0.7079. Will I be doing some wrong calculation?

[@eceonder7770]

Is it right?

[@Raphael-rk1pl]

Thanks man

[@sayanthbonala5638]

Sir what if cut off frequency not given How to calculate it Please help me out

[@ALLABOUTELECTRONICS]

You must have been given the passband and stopband frequencies or the order of the filter.

[@sayanthbonala5638]

Order is 4 sir

[@ALLABOUTELECTRONICS]

And what about pass band and stop band frequencies?

[@sayanthbonala5638]

Order is 4 sir

[@sayanthbonala5638]

ALL ABOUT ELECTRONICS passband=0.25*pi Stop band=0.4*pi

[@mouten1889]

thank you

[@justicehunt7136]

has anyone designed filter in hfss? if yes kindly let me know

[@believethat6739]

If video is on chebyshev filter why you mentioning salnkey filter

[@ALLABOUTELECTRONICS]

Sallen-key is filter topology. Here, the chebyshev filter is implemented using Sallen-key filter topology.

你的视频很优秀，但是我的英语很不好，所以有时候听不懂你在说什么
