[@aaronfritz6892]

Seriously, its so weird having a college professor jump straight into how to derive these concepts without explaining the concept in terms of what its used for or how it relates to other things. These videos are what fills the gap for me, thanks for making this intuitive for a beginner!

[@sanjayprabhu6909]

hello neso i am really happy you are uploading vedios continously thankyou very much

[@PunmasterSTP]

Initial value? More like "Incredible; thank you!" These videos really are quite splendid.

[@maharjaveed8289]

Good method and easy to understand
Again your's work is very Good

[@balasubramaniyans1426]

Excellent explanations sir

[@mohammeduzair1276]

I can't believe the fact that such amazing videos have such few likes!

[@rahulguptha3131]

Nice video thank you we need more videos like this

[@ippalavalasaanusha3672]

Thanks a lot neso academy for the great explanation

[@gowriv944]

Nice sir.upload more and more vedios about control system.

[@sohelansari-dq5kv]

great teacher

[@NitinSharma-so9hg]

Good Lecture . THANKYOU

[@patriciaa4260]

Thank you so much! You have helped me!

[@hikmathasanov]

For the first condition, I think it is supposed to be s.F(s). That is how it was explained before at Signals and Systems Lecture Series.

[@sarojinivaradharajan5598]

Great! Thank you very much

[@s.m.senses7199]

thanks Sir🙏❤

[@kaverik.thekodda]

Is the value of u(0) & u(inf.) just equal to "1"?
See 01:50
I ask because, we determine the value of the function using only the term with the exponent.
(or that's how it seems)

[@kaverik.thekodda]

does the question makes sense?

[@comment8767]

u(t) looks like it might be a step function .... is is not just anything. So is does equal 1 at times later than zero.

[@Happiestsoul31]

Thank you

[@aaqibrashidle6655]

Uh r great sir

[@triposat]

Please upload the lectures of Data Structure as soon as possible. please sir 🙏🙏

[@nesoacademy]

Sure 👍

[@vectorrehan9340]

thanks a lot

[@vinayaaaaaaa]

Sir please upload transient analysis🙏😭

[@harshitpandey8696]

❤️❤️❤️😭😭😭tysm

[@pawandabad5263]

Nice sir

[@sudeepshetty4530]

In final value theorem 2nd example, how do you say F(s)=1/(s-2) pole value is 2? No clarity given about direct conclusion of RHS value?? Can you explain more..other than that quality of explanation is super.

[@PunmasterSTP]

A pole is a value of the variable that makes the denominator of a function equal to zero. Because the factor (s - 2) is in the denominator of F(s), we can set s - 2 = 0 to see that s = 2 is a pole.

[@shraddhajalwani5481]

sir please upload the power system video 🙏🙏🙏🙏❤
you have uploaded 26 videos only please complete it ,

[@agjhv3835]

5:38 but the example you took is discontinuous at t =0

[@PunmasterSTP]

Yeah I was a bit unsure of that part as well. I think the main idea is that the function can't be discontinuous immediately after t = 0, as in, f(0+) is finite and the limit of f as t approaches 0 from the right is f(0+).

[@chidanandadatta4695]

Can we say, result from final value theorem as dc value of the system??

[@comment8767]

The value of u(0) in Example 1 is unclear. If u(0) = infinity, then IV would be infinity, no?
Maybe u(t) is a step function at 0? It is not a generalized function?

[@serenasavage9842]

For final value theorem, how does 1/s+2 = 0 if s=0? I don’t understand what I’m missing

[@akshaymatsagar1710]

sir please complete the paylist .............we r waiting for further lectres

[@akshaymatsagar1710]

[@shreyashagrawal2264]

If we do Inverse Laplace Transform of F(s) = 1/(s+2) then it will give us f(t) = e^-2t and therefore f(t) violates the condition 1 i.e. f(t) = 0, t

[@ahasnainkhan9622]

f(t)=e^-2t.u(t) for F(s)=1/(s+1) not just e^-2t, hope answered your question.

[@-DanishShafi]

There is a mistake in the initial value in the first example.
It's answer is 0 not 1

[@Muvva_raj]

In first example e power zero is one ....but side of that we have u(0) whole will become zero no?

[@mohamedabdulraseethma9568]

u(t) is an unit step function whose value at t=0 is equal to 1.

[@sushrutmdhakate9874]

If final value theorem is not apllicable , then in all cases is that unbounded ?

[@javaandroid6964]

Explain more

[@albertdot5704]

If system is marginal stable, will final value theorem applicable,??

[@talhafaraz6510]

If any one have the lab report on this topic please share with me as soon as possible

[@dungaajay6085]

u(t) is not defined at 0 right..then how e^0.u(0) = 1?please explain

[@johnaime213]

that is why they use 0+, meaning slightly after 0.
