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

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

  When h(t) and x(t) are both zero for values of t less than zero, the limits of integration become 0 to t. When h(t) and x(t) are non-zero for all values of t, the limits of integration are -infinity to infinity.

  Thank you for the explanation! Since almost every example of convolution I&apos;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!!

  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!

  It was a very good explanation! <br> <br>I&apos;m taking the course of Automatic Control, and the convolution videos that you&apos;ve posted has been a huge help. <br> <br>Thank you so much! <br>

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