#19 Finding number of poles and zeros in passive circuits 

A very good video for brushing the basics.. Always crispy and precise in delivering content... kudos👏👏👏

Very good and simpler explanations. Thank you

Sir, kindly explain the concept of zeros using phase shift also. I have found that useful at times. This video is indeed very clear and useful.

Amazing explanation

Extremely helpful. Thanks for sharing.

Wow, that was a awesome video, thanks for that. You got a new subscriber, thanks! Have a good qualitative feeling about zero and poles in circuits helps a lot!

Fantastic tutorial!

Great video... kindly come up with more videos on practical analog design..

simply great and really helpful

Beautifully explained

Also, in the last question with two tanks, in the strict sense we should say circuit has "maximally" 4 poles and maximally 4 zeroes. E.g. with matched tanks, i.e. L1=L2, C1=C2, and all R are same, the transfer function is exactly 1/2 without any pole or zero (due to exact pole-zero cancellation). Any mismatch in tanks can help in seeing both peaking and notches in the transfer function (due to mismatched resonances)

Waiting for similar videos which explains about poles location ideas, poles and zeros in active circuits..Thank you

Very useful explanation

Upo vizuri sana. nimekuelewa

Waiting for continuation video as you mentioned... thank you

Interesting video. RC-CR is a good LPF-HPF transform. A more generic transform is RLC-CRD transform (where D is FDNR) preserving the transfer function.

Nice

well explained. thanks sir

Extremely helpfull

Thanks sir very helpful 🙏🏻

useful video

Query on zero, kindly help: @10:15 what's the meaning of impedance (r1 || c3) to be infinity? We are taught that if two resistors are in parallel, the equivalent resistance is always lesser than least of them, so what is being missed here(it's true only for passive elements). I was guessing that the intuitive meaning of this impedance being infinite is that at 1/(r1*c3) frequency, when vin is applied, no current is drawn by (r1 || c3) from vin. But in such case where will vin drop across to satisfy kvl and kcl?

Great video! Is there any theory or analysis why # of poles is equal to the number of independent elements?

Hi Sir, nice lecture. I have one question, so like zero where output goes to zero what can we infer in case of poles? Is it the frequency bat which output hits max value that is it gets saturated? Please give some analogy and shed some lights on it. Also, as can be seen that for pole frequency instead of getting saturated the output voltage starts to drop at pole frequency. please help. #AnalogSnipets

Hi there, interesting lessions.I want zero out a butterworth low pass filter? how we do that, I see that the zero and poles now in a more easy way thanks. I need a lowpass with more poles and zeros, and will use a opamp for it.

👍
