Convolution Example-Two Rectangular Pulses (Edited)

[@DK794]

it's 12 am here and I've got an exam in a few hours. After struggling for hours to find an intuitive explanation for convolution, I came across your video, and believe me, I can't thank you enough.

[@clarissebonacina9240]

I have an exam tomorrow and I want to express my gratitude. Thank you.

[@BenskiGameWorks]

One of the best explanations for convolution! after a whole course of Fourier Analysis in Uni I have a lot of basic holes in my understanding, and you have helped me a ton!

[@lifeisbeautiful4644]

I don't know how to thank you, you are just great! You literally made me understand this. Thank you professor.

[@712Rm]

honestly, you're a life saver! You're tutorials are amazing; very well organized and very explanatory!

[@vsprasannaa]

He already did! The plateau depends on the widths of the functions in question, if they have the same width, we get a triangular waveform.

[@vasiq44]

This is no doubt a very good explanation of the convolution using the graphical method. Two thumbs up! However, it would be slightly more helpful if you had chosen different pulse values, say 2 for x(t) and 3 for h(t).

[@simonstanev2923]

When videos are slow you don't miss anything. If I haven't watched the previous videos, I wouldn''t be able to understand it.

[@747-pilot]

Wow! What an amazing and detailed explanation that was! I'm taking a Signals and Systems course at Berkeley and had a very hard time with this flip and shift method (both fDT and CT). Your super-detailed explanation was the only one that was able to make me understand this with CRYSTAL clarity. Thank you very much!

[@lilhorsechoka]

My professor has a heavy accent so this definitely cleared things up for me. Thank you very much.

[@sdw4527]

Thank you so much for these videos. I completely understand this convolution concept and aced my exam thanks to you :)

[@CiellyCardoso]

Thank you, it really helped me!! Keep up with the good work! Greetings from Brazil.

[@mahakhan9762]

you're right, this example does show up everywhere. thank you!!

[@estefaniac8260]

Thank you soooo much! Your video and explanation were incredibly helpful. I love how you use graphics and bright colors, I really understood this concept thanks to you.

[@GiveForaSmile]

This is making much more sense now.

[@ehsan_kia]

The convolution of x and y is DEFINED as integral of x(t)*y(s-t)dt, and the definition follows from how it was derived in the first place (as the impulse response, which has to do with delta functions and how those work).

[@alfredlefosa3867]

Thanks Darryl. Finally convolution makes sense

[@libervolucion]

No words, just.. Thank You.

[@nondumisongcobo2867]

Thanks a lot @Darryl_Morrell. Convolution makes so much sense now.

[@GiI11]

Thank you so much, dude! Now it's clear to me that convolutions are an algorithm. It makes no sense to think what the integral evaluates to before doing the 'mirror and run through the interval' bit :)

[@dallasdominguez2224]

Same, I had no idea what the point of convolution was and now Im starting to see that it is an "operation" of sorts that is specific to signals.

[@RobSummers993]

I FINALLY understand convolution. THANK YOU!

[@kimphan4326]

thank you so much its 2am and i just did my first convolution problem correctly and i almost cried

[@Iymonchy]

every time I want to revise convolution I come back to this video

[@chillingmeko]

@ 1:40 why is it a right shift, shouldn't it be a left shift since t is positive?

[@tajiknomi]

Thanks 4 Ur Explanation, But i have a Question... "Why We Flip Up One signal (Either x(t) or h(t)) in Convolution ?? I Want a Logical Answer so that i Know why we Do flipping one Signal ...

[@alonbez5756]

Thank you sir, you explained it very good. Kudos from Israel

[@muhammed_samir_mansour]

from the occupation *

[@alonbez5756]

unlucky for you buddy@@muhammed_samir_mansour

[@flortour9329]

Thank you this example was great! But what happens if convolution includes a rectangular pulse and a function with sin,cos or tan? x(t)=cos(2t) and h(t)=2u(t-2)+2u(t-5) as an example

[@dojodrifter9510]

u saved me so much for my midterm my prof blows so much

[@badgalirri]

Excellent explanation, thank you so much!

[@smiley5867]

very clear and precise! great teaching!

[@Deepakkumar-tq1xv]

Really great and intuitive video 👍

[@saim514]

Thank you so much man You cleared my all doubts. Keep it up man. High Five for you. :)

[@azharhussain767]

A high level matter

[@andrewskyworker]

really good explanation. thank you for your video

[@supermanheavy430]

fantastic example.

[@timothythompkins8653]

Does it matter then where our two rectangular functions lie (i.e. their shift)? It looks to me that if the initial function h(t) was shifted to either the left or right by 5 places, because I'm integrating from -inf to +inf that you'd end up with the same graph regardless. Is this correct? Thanks.

[@anoushpesuna6983]

Very good explanation helped a lot

[@nitrozero3]

you should really do the calculations with the integrals, that would help people understand more difficult problems

[@ec11368]

Thank you Darryl

[@nikeshparajuli6345]

Thanks a lot , this is really helpful.

[@frederikvanballaer3890]

Thank you for the amazing video!

[@CoryEngdahl]

You rock man, great video!

[@Paleoint]

Nice job! Keep 'em coming. Thanks!

[@alanvillaverde4805]

great explanation. very easy to understand. Gracias!!!

[@MrHackerXx]

Thank you bud. That was a very good explanation!:)

[@sHrG78]

Very clear explanation, thank you.

[@jibeneyto91]

Great video! Just to be more rigorous, you forgot to include points t=0,1,3 and 4 in the definition of the convolution.

[@sezinafsenying]

why should h(t-tau) shift to the right when your t=1/2? it should shift to the left isnt it?

[@wesleyrm76]

+Haribo You are adding 1/2 to everything, which moves it all to the right.

[@bobbybrogenlie6177]

Because you flipped it?

[@akshayraut3719]

See bro, when we flip the function, like in this case we have first made h(-tau) and then if we add something, it goes to right and if we subtract something, then it goes towards left, obviously unlike what we do conventionally in shifting.

[@mariochang6335]

h[t-tau] = h[-(tau-t)]. => rotate, then shift to right if t is positive, as usual

[@nehabhakuni]

hii Darryl...you cleared my concept...it really helped me...it will be great if you can help me with the integration and differentiation of a any signal(to solve it graphically)...waiting 4 ur response..

[@TigasFMS]

Very clear. Thank you so much!

[@laautaro11]

awesome video, thanks a lot

[@mnada72]

Thank you for the great explanation

[@abubakrbinumar9635]

skillfully explained.

[@andrewdenterlein6447]

Great video! Thanks for posting.

[@dhiruiitk]

THANK YOU very much,it helped me a lot

[@fikrifirman]

great video. thank you very much

[@mitchss321]

Take my money, my professor doesn't deserve it...

[@InspiredStrangers]

Thanks so much for this man!

[@jasonbullemer8134]

great explanation. Thanks!

[@phomolomphahlele6189]

thank you this is incredible

[@samirandgina]

Amazing explanation thank you!

[@martinschidozieezuma6741]

very good tutorial

[@sarvariabhinav]

his method is correct but for doing further problems please take time t(small t) as the time of the origin for eg if we have a window from 1/2 to -1/2 well take t+1/2 and t-1/2. half knowledge is always bad.

[@summerha8170]

Great explanation ! thank you sir

[@seenathgooding181]

Thanks for the vid. it helped alot

What a jokester: "Click this link for a better and shorter version of this video!" .....video is actually 5 minutes longer

[@TDASS281]

Matt Popovich the other video you saw had 4 parts to it lol you were probably only on the first part

[@heyhey3827]
