I like how you introduce both operators with a graphical representation and then proceed to give a mathematical description. This organization seems natural to me. I also like how you explain the use of each operator. In your introduction to the rep operator, I believe it should be $ k \in \mathbb{Z} $ since you want to allow k to be negative as well. Also, you could clean up your multiplications by removing the periods (multiplication is implied by convention). Great slecture!

The initial outline and the numbering system makes the process easy to see. In the comb example the graph is easy to understand. The function PT does not get explained until 1.1.4 while it is used in 1.1.3. It would be good to explain what that function means

  • Review by Yerkebulan Y.
  •  You provided good and clear explanation of rep and comb both graphically and by equations. You should have also explained impulse train pT(t) graphically. And at the end you just mentioned that comb is a CTFT of a rep. I think it would be better if you also included that rep is CTFT of a comb.
