You're such my "messiah", saving me from the falling of getting E grade in signal and system class... hope this year I'll get at least B grade in this class.
1. Impulse response is only used for LTI 2. If system is not LTI you cannot calculate impulse response 3. When input is unit impulse(2del(t) is not unit impulse , here weight of impulse signal is 2) 4. The output to unit impulse or impulse of a LTI system is known as impulse response or unit impulse response.
thanks to you so much for this video lecture dear i will learn a lot and my little bit concepts are much stronger by this video . thanks again and excellent work please more and more videos upload about this course
Unit impulse signal has unit area or we can say its wieght is 1 and its magnitude is infinite similarly 2del(t) has infinite magnitude but it has wieght equal to 2 so it is not a unit impulse now. Hence it is not considered as we only have to give input as unit impulse. Hope u understood
y(t)=h(t) when x(t)=delta(t) is applied to an LTI system. It is denoted as h(t) because this particular relationship is a defining quality of all LTI systems. If you wanted to calculate the output function given a different input function, then h(t) must be known first to perform the convolution.
h(t) is written as output when input is impulse function. Whereas when we have a generalized input like x(t), then h(t) is transfer function and y(t) becomes output function.
@@drunkirk3472 Why we have to use h(t) to find y(t) when input given as x(t). If iimpulse is input then h(t) is output. Similarly when x(t) is input then we have to find output y(t), but why we use h(t) in finding y(t). Please explain.
when we are finding y(t) , h(t) is response of system whereas x(t) is input. but to get that h(t) [if its not provided], we should find it using impulse response technique shown in video.
@@chembakurusuryanarayana6303 h(t) is impulse response of the system which is to be used for finding output y(t) for any random input x(t) using convolution technique. As h(t) is -IMPULSE RESPONSE, it means we can find it only if we apply impulse signal at input. Hope that clears
in figure h(t) is shown as output of system and y(t) is also used as output of system... How exactly y(t) is different from h(t), if they both have to shown in one physical control system model?
h(t) is the unit impulse response or simply impulse response of the system i.e. the response of the system when the input is unit impulse signal but y(t) is the output of the system in general i.e. the input signal can be any signal not just a specific one.
we are so lucky to live in the era, in which people like you help people who learn to learn easier, thanks!
You're such my "messiah", saving me from the falling of getting E grade in signal and system class... hope this year I'll get at least B grade in this class.
What did you get?
So now tell us what you get????
telllllll me whatt gradeeee u gottttttt???? 👀
@@neeltej4123 i guessing he got F😝
the wait continues
1. Impulse response is only used for LTI
2. If system is not LTI you cannot calculate impulse response
3. When input is unit impulse(2del(t) is not unit impulse , here weight of impulse signal is 2)
4. The output to unit impulse or impulse of a LTI system is known as impulse response or unit impulse response.
Why don't we find professors like him in real life.
Because we never pay attention in the class
bohot sahi padhaye ho boss. hatss off man. seriously hats off to u your hard work and everything
Every video has GOD level explanation
I wonder how can anyone dislike this video!
you are so talented in delivering the concepts in a simple and nice you . may ALLAH reward you paradise . WA NIMAA BILLAH .
thanks to you so much for this video lecture dear i will learn a lot and my little bit concepts are much stronger by this video . thanks again and excellent work please more and more videos upload about this course
Thanks a lot sir, You are the GURU of teaching.
Ur lessons are excellent we r thankful to u ....
thank u very much for your effort.your lessons are the best .
Danke Schone !!
Sir plz upload more n more topics on signal and system ... plz sir be quick ...try to cover whole syllabus ...
thank you very much , best explanation i ever seen , please upload more topics such us power spectrum density & power spectrum estimation
Clear and lucid ♥️♥️
5. Impulse response is fixed for a LTI system. So used to define a system.
Sir please upload lectures on Fourier series Transformation
Awesome explanation .👍
Thank you!
I ask my LOVE (ALLAH) to bless you and save you
thank you for your lacture sir!
great explanation :)
Great explanation
What did he mean when he said that the impulse signal is a fixed signal ?
Great
y(t) is in time domain, x is in tau
After using LT o/p is in time domain
Is it ok with anything In rightside can change X(s) after applying LT
what dose 2 del(t) mean ? (as del (t) has infinite magnitude & unit area @ t=0 )
Unit impulse signal has unit area or we can say its wieght is 1 and its magnitude is infinite similarly 2del(t) has infinite magnitude but it has wieght equal to 2 so it is not a unit impulse now.
Hence it is not considered as we only have to give input as unit impulse.
Hope u understood
please can you explain why we convert multiplication into convolution in IFT?
I think that the Laplace transform of integration from 0 to t x(tau) dtau is X(s)/s. Why is it from minus infinity to t?
Thanku
What is X(t) and y(t) in the fig. given
why we show h(t) instead of y (t) in fig. as output
y(t)=h(t) when x(t)=delta(t) is applied to an LTI system. It is denoted as h(t) because this particular relationship is a defining quality of all LTI systems. If you wanted to calculate the output function given a different input function, then h(t) must be known first to perform the convolution.
What's difference between y(t) and h(t) as both are outputs of LTI systems
h(t) is written as output when input is impulse function. Whereas when we have a generalized input like x(t), then h(t) is transfer function and y(t) becomes output function.

Why we have to use h(t) to find y(t) when input given as x(t).
If iimpulse is input then h(t) is output.
Similarly when x(t) is input then we have to find output y(t), but why we use h(t) in finding y(t).
Please explain.

Sir can you provide video lectures of 'time and frequency domain analysis of continuous time signal'
Please please please
Great videos!
Tq bhayee
what is LTI system?
linear time invariant system
and what is an LTI system?
Sir please raise your voice....its not at all audible without headphones, and its really irritating to put them on every time.
Are you deaf?

Is it possible to find impulse response For Non LTI system
nop
You're not Sal!
