Convolution-What's τ got to do with it?

thank you man

Yo someone’s explaining signals in english for the first time?

Language is confusing

actually tau is just a dummy variable. you can replace it with any other letter, and the result will still be the same.

thanks, i've had an Eureka feeling here. Now sounds clear to me. Sometimes signals has too much symbols and I feel a bit lost

Why is the integral of the product of functions just the area under the ‘exponential’ function? Is it because the other function is always equal to 1?

Amazing convolution

Thanks ! Very Usefull

the only thing i remember from class is "tau is a dummy variable!!
but your explanation makes more sense lol

Thanks,
A question, while tau domain is from minus infinity to positive infinity, why you use just positive values?

Ok, so basically τ is used as a consequence of 't' being used for the time shift

Thank you! This is exactly what I was missing to link the intuitive flip-and-sweep idea to the equation in my mind.

One more step towards complete understanding. Thank you.

THANK YOU VERY MUCH FOR EXPLAINING THE CONCEPT. Now I feel like an idiot for not seeing that Tao was a right shift (negative) or left shift (positive) along the x axis with respect to the function acted on. Now to solve some DE convolution Tao problems!

This is really helpful and detailed, thanks for this

Thank you so much for explaining this! It's nice to now have an understanding as to why tau is used instead of just using it blindly!

and no indian can explain something like this

Thanks for sharing this knowledge!

love it

The thing confused me was the function h(t), now I know it acts as an indicator in this example, it has value of 0 or 1, indicating that whether we should integrate the value of f(t) in position t. In other examples, it may acts as a weight rather than an indicator, but they are the same kind of things.

Really you make everything clear,I like that.

Great explaination sir... 👌👌👌

So in this example what would you get for tau=2?

h(2-(3))=h(-1)=1?

haha well done, but I'm still confused.

great video on how it works, now i just need to find out why it's done :)

I thought I was stupid for not understanding all of this stuff in my signals class...turns out I have a horrible professor and textbook. thank you for finally making things clear. Colege would be sooo much easier if professors were actually good at teaching.

very beautiful

fuck I hate this, still lost.

I wish I had you as my prof

thanks very good explaination keep it up

THANK YOU!!!!!!!!!!!!!!!!!!!!!!VERY MUCH.

THANK YOU

even i had same question why tou has to got to do..thanks for explanation

Thank You! Great explanation!

Finally I got it! The best explanation!

Thankyou!!!

Thank you very much

why you don't make videos for emf??

saddaam

I love the way you explain a very complex concept in just a simple way !!!...... Too GOOD Sir..

A good way to understand that flip and shift thing is like this - 
h(t-T) = h(-(T-t))
I think if you re-write it like that it makes much more sense

your engineering videos are top-notch. Thanks for explaining clearly. I wish you were my professor!

Thank you for the explanation! Since almost every example of convolution I've come across with used even functions, I never understood why h(t-tau) is used. Now I know that it is to reflect the function. I still need to build more intuition and practice, but this video gave me a good push in the right direction!!

amazing video

thank you :)

the convolution the better song of the cult

Prof, why are you calculating just the area underneath the function x(tao) and not under h(t-tao) as well? Aren't you multiplying the two functions first before integrating?

Thank you Mr. Morrell for these amazing, concise videos. I was completely lost at convolution, particularly with the whole Tau variable part. Your video was EXACTLY what I needed, an extremely thorough explanation of why Tau is involved and now I am able to understand the convolution process entirely. Thank you again and I am now subscribed to your amazing channel, your work is very appreciated!
