I do math for recreation often and these videos have helped my understanding so much, starting with the one about the convolution of two box functions being a triangle function. Thanks so much!

Thank you very much. I've seen your videos about signal and system and it's really help me to understand this subject. Once again, thanks Mr.Morrell.

Clear and simple!!!.
Are you planning to make a video about Fourir series ?

I have a question... at the part when you flip and switch h(t) to h(t-T), in this case.. you simply change t by t-T? no matter what the function by which h(t) is defined... you simply do that?

@gzimih Yes, but probably not until the beginning of November.

I'm a beginner... can someone tell me what does TAU and T mean? What does it mean that we subtract tau from t? I can't visualize this.

@Jdonovanford See the video that I have posted in the comments. It should explain the mystery of t and tau.

Sir, why are flipping at 2:20. Shouldnt we just add t to our orignal signal h(t)?

@ChevyVanTwenty aha! look at the axis, it is tau axis. It would be wrong if it would be t axis instead. t in this case is phase shift and not a variable. Variable is tau.

@Jdonovanford Ah, you mean "Convolution-What's τ got to do with it?"?

@DarrylMorrell That was awesomely explained! Thanks a trillion!

tau is dummy variable.U can use other name for that variable...like z, x, y
