[@yky1360]

good video, but why we need to make the result of LC and CC the same? why they need to be the same?

[@srinaath9845]

Thank you bro you've been helping for all my semesters👌👍

[@anarisnoveanu6778]

I think you should change the title because I watched the video hoping to understand the difference between the two, but I just learned how to transform from circular to linear. Not a bad thing, I did learn something useful, the methods were interesting because I always use formulas but now I could use this in some problems since it is shorter.

[@Rpk595]

direct and simple explanation , you should increase viewers ,it will help many engineers

[@ShrenikJain]

sabbani mahesh I cannot increase viewers ... You can :) By sharing videos 😀

[@Rpk595]

Shrenik Jain you have to explain these type of videos , when I search a topic your video should be seen in search results

[@Rpk595]

Shrenik Jain search on KZbin and workout on how your video can be seen on top of search results, your content is awesome man. Keep it up 🎙📈⬆⬆⬆⬆⬆

[@ShrenikJain]

sabbani mahesh Ty for appreciating 😃

[@ShrenikJain]

sabbani mahesh Yeah I did some search engine techniques

Awesome explanation 😀😀

[@ShrenikJain]

Ty 😃

[@veneky01]

Suppose if we solve by this method for both problems seperately will it get consider?

[@bhaskaralakshmiganisetti3779]

Can u plz tell me these methods only applicable for discretectime ...what r the shortcuts for contineous time for fonvolution

[@ritwiknandy9037]

Thank u sir ....thank u so much

[@ninaddesai5144]

thank you so much.

[@bilalbajwa3407]

for circular convlution what if the length of x is shorter than h, then what?

[@sandhyajoy3008]

Awesome lecture..

[@ShrenikJain]

+sandhya shree 😃

[@sandhyajoy3008]

Shrenik Jain Sir.. Y haven't u solved Convolution using graphical method?i checked out videos of various channels but I'm not satisfied.. It wud be better if I learned ur lecture :/

[@venkateshpolisetty5624]

u told by making equal samples x(n)=h(n) using L+M-1 formula in another vedio of urs but , u didnt used it here and made x(n)=h(n) bby adding zero to h(n).. this can be done in any circular convolution sum? i mean to say zero padding?

[@reshmaslukose6424]

Thanku somuch

[@rforrohitarorasirclasses6500]

Nice content your

[@sohail-one]

Bro but n=0 point is imp to mark ,what to do about that 😕

[@MARUTI96]

Super

[@powerkumar7392]

Why '(0)' is not put intially in sample. For padding

[@jitmondal9313]

Sir is this method applicable for find the linear convolution using circular convolution?

[@vinaypokharna6912]

Why in one circular convolution you are using zero padding and in next video you are using l+m-1 to make length equal.....so what is the difference

[@Karthik-kt24]

thankuu

[@ESEben10]

And which are the advantages of circular convolution?

[@rakeshkarmakar9168]

In overlap add method we write h(n) in the 4×4. Or 6×6 whatever But here we r writing x(n) in that sq. Matrix why?

[@shadanakhtar1437]

Sir if x(n) having 5sequence and h(n) having 4 Sequense then how we add 0 in Circular convolution plzz reply sir

[@uniqueversalunicorn2412]

Thank you dude...

[@khadarsayed2878]

great sir!!!!

[@ShrenikJain]

Thanks 😃

Sir,graphical method par v kariye...

What if when h(n)=sin(3¶n/8)for 8point circular convolution

[@tusharsonawane1797]

if i directly do zero padding without checking both answers, that's fine right ?

[@mohamadelghouti5070]

thank you :D

[@ShrenikJain]

Welcome 😃

[@manishjoshi4697]

Nicely explained 😊 But this method won't work for 8 marks ques😂

[@shivanidashore8175]

Thank u

[@ShrenikJain]

welcome :)

[@shritejkashid4631]

Sir last method if I use 6*6 for h(n) and 6*1 for x(n) still answer will be same or different , is it valid??

[@darlzchriz1320]

I don't think order matters

[@jasonjimbun2686]

Hello, there guru, What if the origin of each signal x[n] and h[n] is different? I mean the position of 0

[@ShrenikJain]

JASON JIMBUN Then after linear convolution... Range of n in answer will have Least n value = least among (x1,x2).. Highest n value = highest among (x1,x2) Highest n value

[@jasonjimbun2686]

Sorry let me refresh the question again. If I have this question, x[n]={4 ,1 ,2 ,5) , with 1 as position 0 and h[n] = {1, 2, -1}, with 2 as postion 0, how do we solve it using Circular method?

[@ShrenikJain]

JASON JIMBUN Make size same and solve.. Ans will have least value of n as -1 and highest value as 2

[@jasonjimbun2686]

Nice, now the question twist a bit, What if x[n]={4 ,1 ,2 ,5) , with 4 as position 0 and h[n] = {1, 2, -1}, with 2 as postion 0. Using Circular Method should I have 5x5 5x1 matrix? including the zero padding

[@ShrenikJain]

nop.. 4x4 with least value as -1 and highest as 2

[@shaguftajilani1064]

My exam is after 2 hours and i am here 😂

[@pallavinarwade1546]

If x(n)=&(n)+&(n-1)-&(n-2)+&(n-3) and h(n)=&(n)+2&(n-1)+3&(n-2) find y(n) linear convolution ..... Plz send linked of this example &is del

[@ashuk9]

Sir plz add a video to find linear convolution using circular convolution

[@ShrenikJain]

Swayam Prakash This video is that only... Using circular conv. you can find linear conv. By zero padding concept

[@ashuk9]

Shrenik Jain Sir i am facing a bit doubt for solving the problems on finding linear convolution using circular convolution

[@ashuk9]

will u plz upload a problem like that?

[@ShrenikJain]

Swayam Prakash In this video all steps are mentioned .. Follow it carefully

[@ashuk9]

Shrenik Jain ok sir
