You are clear about your thought process in both proving the periodicity property and computing a DTFT. This can be helpful because those general concepts can be applied to other similar problems. I also like your use of color to indicate the what term in the expression your are talking about. In your second computation, remeber that the DTFT is a continous function and therefore you must use the continous delta function, which is infinity (not 1) at a single point. Good job overall!

I enjoy the flow of this Slecture and the use of color to highlight the use of certain variables in equations. I also enjoy that the Slecture is short and sweet which makes it easy read and process. If there was one caveat I comment on it would be that in the last line that the DTFT of the complex exponential is repeated every 2*pi. Other than that is a great lecture, good job!

What I liked most about your Slecture was the use of color to emphasize the replacements in equations, since it is really helpful to clearly see and understand what you are talking about. Great job!

Making this slecture with a few different colors to emphasize the exponential and the delta values. The overall slecture felt a little bit short in lengthwise, however, this slecture clearly explained the topic. Nicely done!

I really appreciate the use of different color to show the importance and point to notice in your demonstration. Because it is just something I could potentially miss. Thanks for pointing that out to me. And if you could provide some graphs it will be better for others to understand your examples.
