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

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.Anyway, good job ! I understood a lot from your lecture. )

The outline is very helpful to understand this topic, especially when I wanted to make sure I was following this slecture. The graphical explanation was done perfectly and the mathematical expressions were good as well.

I really enjoyed the use of graphics to illustrate what a rep and a comb function look like. It really aids the understanding a lot! The flow seems very natural to me and I think it has a very good structure and explains the mathematics in terms that are easy to understand and follow. My favourite feature of this Slecture would have to be the link in the references to the list of YouTube videos where one can get more information if desired. Great Job!

A very clean slecture, which is very good because it makes it easier for me to follow and understand. I like how you structured your slecture from basic information to detailed information about the topic. Short, concise and understandable points which helps me understand. Overall, great slecture.

The work is very clear and well organized. It is really easy to understand the definition of rep and comb by looking at the graphs. It would be better if you state the relationship between rep and comb.
- Review by Andrew Pawling
The use of the figures to demonstrate the operators is great! I would recommend showing what happens with the rep operator when T < a+b. The text descriptions are good but could use some rewording. Some ideas that you are trying to convey are not exactly clear in the text descriptions.
