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.

[DarrylMorrell]

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

Clear and simple!!!. 

Are you planning to make a video about Fourir series ?

[DarrylMorrell]

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

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.

[Jdonovanford]

@DarrylMorrell That was awesomely explained! Thanks a trillion!

[DarrylMorrell]

@Jdonovanford Yes indeed. Hope it helps.

[Jdonovanford]

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

[Jdonovanford]

@DarrylMorrell Which video?

[sandslash123]

@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.

[ChevyVanTwenty]

didn't you time-shift h(t) the wrong direction? or maybe im just drunk...
