Gain Margin and Phase Cross over frequency 

thank you... you're doing what my tenured professors at the university of southern california, USA cannot: TEACH.. truly helpful and amazing. i will graduate because of your videos

Sir you have explained far better then my so called BIg GATE institute , You bring me to the easiest way to find out Gain Margin, Thank you very much, Have a nice day

YES! FINALLY! I was pulling out my hair trying to figure it out from my notes and you clarified it. Thanks a lot, you rule!

Oh men, you are such a Savior. Bless🙏🙏

Very simple explanation sir thank you very much sirr 😊

actually i'm Nigerian i like this lecture i have exam next week 10/09/2019

I have an exam on 17th may n I watch all of ur video's for preparation sir...u r awsm sir...

Thank you sir You cleared my all doubts about this topic.

A legend among men. thank you

YAY!! THANKS A LOT, have been looking for the step by step procedure for this and now I know it. Thanks again MAN... Keep posting :) Would like to know this step by step process for PHASE MARGIN too :)

You make very easy topic now thanks 👍

I watched this RU-vid video about phase margin and gain margin, but I must admit that I was a bit confused and couldn't fully understand the concepts being discussed. It's possible that the video was intended for a more advanced audience, or the presenter didn't explain the ideas in a way that's accessible to beginners like me. I also noticed that some people in the comments were applauding the presenter's explanation, which made me wonder if I'm missing something. However, I understand that everyone has different levels of understanding and familiarity with the topic, so it's possible that they had a better grasp of the concepts. If anyone has any resources or recommendations for learning about phase margin and gain margin, I would greatly appreciate it! I'm eager to learn and understand these concepts better.

simply superb sir

explanation is good but you should keep the camera stable as it is creating disturbance in understanding

Thanks Man , Very good Explination

lol when he used the calculator to determine 1/sqrt(2) and its output was sqrt(2)/2. All the same, good presentation! :)

it is very helpfull thank you chinmaya

Brilliant, but let the audience know that k = 1 so it is K/1/Kg then -20log(answer) in Db ..many thanks!

Very helpful, thank you! How will I use this to find the phase margin?

you are awesome..it just cleared my every doubt

thank you so much :)) greetings from turkey :)

how about any other transfer function with numerator ? E.G. k(s + 1)

You are doing a great job sir how do we find bandwidth and DC gain of a simpler transfer function..thanks in advance

For separating the real and imaginary part, don't we have to rationalize the fraction?

Do it for phase margin and gain crossover frequency please.

Excellent Work. But, do you have video to show how to find phase margin without plotting?

What would you do if the number on the top wasn't 1 though? This is where I am stuck

Excelent!! Thank you

God bless you

Your videos are amaaaaaazing! Very helpful. Thanks! I am a student of Murray State University, KY and I have an exam on 30th of May. Can you please upload a video on lead compensators and lag compensators via root locus? It'll be great!

i love your video! but how to find phase margin for this question?

Absolutely impressive 💓💓

Thankyou so much :) it really helped ,can u please upload how to find phase margin as well

Thanks very much bro..... what if the numerator is not one?

thnk u sir....helped a lot.... :)

WOW! THANK YOU SIR

Thanks a lot for this video......

Thank you sir

hey sir, i really like your way of explanation, i'm just confused about one thing, is the crossover phase frequency the same as the phase margin? if not, pls tell me how to get the latter and thnx

i like your video

THANK YOU KKINGGGG💕🛰

for gain margin there will be a negation before 20log(kg) formula.

It's unreal explaination. I am very much impressed with your provided solutions. Could you please help me resolving following transfer function : 1/s(s+1000)2 . Find GM. where gain coefficient K : 630 x 10 power 6.

Sir could u please find for same problem phase margin and Gian cross over frequency

THANKS A LOT SIR....

shouldn't the imaginary part be obtained by multiplying the denominator and numerator by the conjugate of the denominator? because we can't separate fraction in two fractions, one the imaginary and the other the real part, till the denominator isn't expressed in factorised form and the numerator is an algebraic sum of real and imaginary part

Can i draw bode plot on normal graph if log graph is not given in exam?? But how??

Nice video, nice english

please upload video on phase margin also

Is it phase cross over frequency or gain margin. That he is finding out

how do you do it when you have a zero in the function?

how about estimating phase margin with given transfer function?? can u pls post a video on that too.

Thanks dude!

Thanks Sir !

Thankyou sir..

sirr plss upload video on niquist plot

thank you!! very much!!!

grt vedio sir

How Phase margin calculate

Thanks!

thanks .

It was a good video :)!!!

is the phase crossover frequency the same thing as the gain crossover frequency?

thanks for clearance....

Thankyou Sir

very good

Just one query: For Phase crossover frequency, you said to equate the Im[G(jw)]=0. But actually you equated the imaginary part of the denominator of G(jw) to 0, i.e, without rationalizing G(jw). So, please clarify you mean to equate the denominator only or the whole rationalized transfer function.

Help full to me bro

how to find out phase margin and gain cross over frequency without plotting bode plot??

@6.45 while calculating gain margin you have not considered the imaginary part by saying it is zero.. Can you please explain it..

sir upload phase margin video nd one thing more when cross over frequency is 0,then gain margin will be?

hi, i want to know how to find the gain margin for time delay? do we have to apply euler rule

Sir what to do when there is not 1 in numerator???

How can i get the phase margin? Thank you

For the phase cross over frequency, why is it required to have imaginary part of the transfer function equal to 0?

superbbbbb...

Hellll...i am not getting why in finding phase cross over frequency we need to take imaginary part as zero...some1 plz ans

Thanks buddy

can you give me idea about to find phase margin from TF?

Can you do phase margin please

please add Nyquist plot ...

tanks more....

awesoooome man thanx alot but i also need the phase Margin if you dont mind .....^-^

Wat happens if imaginary term comes in numerator also..

Can Wpc be zero??

Grt ! onee Thank you !! :)

Thak you ♥

Explain slow sir and tell clarity its very understand sir

Can't we take w^3=1?

Why was the function not rationalized before making calculations?🙄

NICE One

Wg ?

thanks for:-)

TF must be L(s) = G(s)*H(s) loop TF where H(s) =1.

Wpc. Y u took IMG part 0

4:07 Kanye in the house :P

You didn't find the phase margin and the gain cross over freq.

sir where is phase margin

c'mon yaar. every engineer knows 1/sqrt(2) is 0.707... Its in our blood. We don't need to check it on calculator.

Cool but u didnt calculate phase margin
